Charles,<br><br>I understood from Darren and Stefan that OpenSim's target is to be the server for all kinds of applications. For this goal to happen there would be own plug-in component for the SL Viewer, own for realXtend, etc. I naturally agree that the current LL Viewer is the mainstream now and the compatibility with that can not be broken. <br>
<br>If we follow the plug-in approach for different viewers, then it is no longer an issue whether realXtend client is compatible with LL Viewer, right? When using realXtend server, you have a setting whether you run it as a standard OpenSim or in realXtend mode. I think this is well aligned with the goals of OpenSim. <br>

Hi,<br><br>The LL viewer is supposed to login only once and stay connected to that place for the whole session.

<p>Currently only realXtend viewer can be used, but I wish that
in the future there will be more support for this architecture. We maintain the
realXtend viewer so that it can be used to access also SL servers or standard
OpenSim. The avatar appearance from avatar storage can only be seen by others
on realXtend servers. The architecture needs support from both server and
client. </p>

<p style="margin-bottom: 12pt;">Hi,<br>
<br>
Some comments how realXend has implemented things:</p>
<div>
<p>2008/4/10, Michael Wright <<a rel="nofollow" href="mailto:michaelwri22@yahoo.co.uk" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">michaelwri22@yahoo.co.uk</a>>:</p>
<p>I haven't been able to find too much on how the RealXtend avatar system is
really going to work. And while in some ways I think its a step in the right
direction, it also seems to limit a lot of things. I'm not so sure you
should alway have the same avatar for everything. Or should completely cut the
"region servers" out of the whole process. If I teleport to a region
that has a role playing game, maybe my avatar should automatically change (at
least clothes, but maybe body as well) to fit into that game. So the region has
to be able to have some say over the avatar. </p>
<div>
<p><br>
The current realXtend login process gives a control point for region servers as
well. When a user logs in to a region, the viewer sends URL to user's avatar
storage. The region then sends that URL t other viewers so that other user's
can see each other's avatars. It is possible that in e.g. a strict role playing
world, the region uses it's own avatar storage which stores a special avatar
for just that user. Then the region server sends URL to that avatar storage
instead of the one that viewer sent to the region. If we want to get really
smart here, it would be also possible to combine something from the user's
regular avatar to the role playing game avatar to achieve nice results... e.g.
using face form from user's regular avatar but otherwise using region specific
body and clothes. </p>
</div>

<p> </p>
<p>I have the same sort of thoughts about inventory. While it should not be
centralised, the regions do need to be able to (with permission) do certain
things, like maybe a region gives you a extra set of folders for use in that
region, but they disappear when you leave it. I am also not sure there should
be just one inventory set for each user. Why not a number of sub sets that can
be combined etc. Maybe the region could restrict access to only a certain set,
which might be a set that it provides, when in that region; no space ships when
in that serious business region.. Inventory really needs to swap to a more url
based system. </p>
</blockquote>
<div>
<p style="margin-bottom: 12pt;"><br>
We are just thinking how to build all this in realXtend. Currently we have
thought that each user will have a region specific inventory and a personal
inventory. The personal inventory is stored at avatar storage so it will travel
with the avatar. </p>
</div>
<blockquote style="border-style: none none none solid; border-color: rgb(204, 204, 204); border-width: medium medium medium 1pt; margin: 5pt 0in 5pt 4.8pt; padding: 0in 0in 0in 6pt;">
<p>Also we need to remember not everything will be interconnected. There will
be some applications (or possible grids) that want to be separate from
everything else. <br>
<br>
So I don't think we should be forcing any centralised system on people. And yes
from what I've read, I actually think the realxtend avatar system sounds too
centralised, but that could be because I don't know enough details of what is
planned. I'm not saying its wrong, it just doesn't fit all possible uses. So we
need things to at least be modular. </p>
</blockquote>
<div>
<p><br>
Currently realXtend components have been designed so that there are no
centralized control points, it would be really a bad planning to build such an
architecture on that kind of centralized assumptions. In realXtend
architecture, everyone can set up their own avatar storages and user
authentication services and decide to trust or not to other user's
authentication services. <br>
If a virtual world hosting company wants to make a completely walled garden
solution with realXtend, that is also possible. They can set up their own
avatar authentication and storage and trust no-one else's authentication server
(there is a basic allow/deny setting for this). </p>
</div>
<blockquote style="border-style: none none none solid; border-color: rgb(204, 204, 204); border-width: medium medium medium 1pt; margin: 5pt 0in 5pt 4.8pt; padding: 0in 0in 0in 6pt;">
<p> </p>
<p>Having said all that, of course I think a lot of people and applications
will want to have shared resources like these. Just we have to be careful in
how they are implemented. And for opensim at least, that should be a open
process/design that everyone can be part of. </p>
</blockquote>
<div>
<p><br>
A team of people almost always reaches better solutions over individual. All
the different use cases should be covered in a great care. I hope that
realXtend initiative with the distributed avatar architecture is being refined
with the OpenSim community involvement. I am sure that there are still many
things that need addressing. The realXtend code is available at <a rel="nofollow" href="http://sourceforge.net/projects/realxtendserver/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://sourceforge.net/projects/realxtendserver/</a>
and as I mentioned in my earlier mail, we will have a new version, which is
based on current OpenSim, soon available.<br>

Short answers. I don't know, and no. The process for code coming into<br>
OpenSim is to put a patch in mantis. I haven't seen any proposed<br>
patches in this area in mantis.<br>

Hence you've created the paradox. :)<br>

Honestly, this is a hard problem to solve, and one that seems a bit<br>
beyond the current scope. That being said, implementations and research<br>
in this area which work with OpenSim are always welcomed.<br>
