[Opensim-dev] rex auth & avatar systems (Re: future rexviewer merger)

[Charles Krinke]

Dear Crista:

Perhaps you can help me understand a couple of things.

Is it true that an avatar on an OpenSim grid, such as OSGrid could teleport from a HyperGrid enabled region on OSGrid to another OpenSim grid such as UCIGrid and end up with an avatar identification such as <first>.<last>@osgrid.org?

For instance, my avatar is "Charles Krinke". So, would I end up on UCIGrid after the HyperGrid teleport as "Charles.Krinke at osgrid.org". At that point, would I expect to be able to access my inventory back on OSGrid while on a region on UCIGrid?

Before getting too deep into permissions issues and partially finished logic, my current thought has to do with a simple concept. That is, capitalization. I would argue that "charles.krinke at osgrid.org", "Charles.Krinke at OSGrid.org" and "cHaRleS.KrInKe at OsGriD.ORg" are all the same avatar and I wonder if we are considering that notion?

I also am assuming that the reverse is either working or contemplated. That is, a user on UCIGrid teleporting from a HyperGrid enabled region on UCIGrid to a HyperGrid enabled region on OSGrid and would end up on OSGrid as <first>.<last>@ucigrid.edu and similarly be able to access his/her inventory back on UCIGrid.

Perhaps you can help me understand some of the nuances as we look at this brave new HyperGrid idea.

Charles

With the Hypergrid it is also possible to roam through different domains 
of control carrying not just the avatar (the carcass) but also accessing 
the user's inventory. As such I would like to understand better what the 
differences are, besides the name.

For example, OSGrid's User-Asset-Inventory trio is effectively an 
"avatar server" in the sense that people who have accounts there can 
hypergrid jump to other grids and still "carry" their avatar and access 
their OSGrid inventory. But that's just the most popular one. Anyone who 
can start a standalone can have their own trio of servers who act like 
"avatar servers" -- at least as far as I understand what avatar servers 
are doing.

In implementing the hypergrid there was no need to introduce new 
services or even modify the functionality/interface of the current 
services in opensim.

So what else do Rex avatar servers do? Why did you have to introduce a 
new service and modify the existing ones?

It's possible to choose only certain users and/or authentication services you allow into your world, but it's also possible to ban certain users/auth. services and allow everyone by default. This makes the system inherently a bit less decentralized, which is a point I agree is an important aspect of the future 3D web.

It is not as simple as having your avatar on a USB stick, but that's of course just a technical challenge for someone to fix if necessary. The way the experimental reX authentication system works isn't very centralized at the moment, since anyone can host them, they're not dependent on each other or anything else. Personally, just like Toni, I prefer to have a service online that I can access from anywhere and especially if I would for example want to send an IM or VoIP comms to a virtual world through a mobile device ("Just a second, guys, I'm on a bus and I'll get to the meeting soon"), I would rather not host the services on the phone.

Anyway, this is a really interesting topic in general and since we are now talking, it would be very interesting to hear everyone's opinions on how this kind of a system should work.
