[Opensim-dev] future rexviewer merger

There are a number of use cases for OpenSim and what Rex has done appears to be a valid use case also. As always, I look to our architects, Mw, Lbsa, Adam and SDague to guide us in OpenSim for the appropriate way to add features and modules for the various use cases.
Having a healthy debate is good, and we are starting to have one on the Rex extensions.
I just dont want the negativism expressed by some to indicate that this is the official position of OpenSim.
We are an open community and embrace new ideas and new technology. So, I say, "Let the debate continue and lets see where we get"

Hi,
I am not opposed to Rex technology. I'm not opposed to have it in
OpenSim.
I'm also not opposed to the people who I know (like you).
What I am opposed to is the strategy of doing Windows-only
development behind closed doors, without community (OpenSim dev)
feedback, then presenting huge patches that are so brittle that they
need to be applied without scrutiny or go stale.
I would welcome Rex involvement if the Rex developers would join us
in -dev, discuss things, and submit small patches that we can
analyze and become familiar with, and modify so they don't conflict
with the directions where OpenSim core wants to go.
Fromn what I gather, Rex is intent on pushing both the login service
and the viewer onto OpenSim. Including going to the point of
breaking SL viewer compatibility. I am totally opposed to this. I
would never endorse a single LL-Code based viewer as _the_ viewer,
to the exclusion of any other, unless it's fully BSD licensed, e.g.
developed from scratch.
Also, I see anumber of abuse scenarios possible with the
login/avatar service (commercial abuse), which is why I personally
favor a different model. Specifically, to keep the avatar appearance
data on the client and not on any server at all.
That is what I can write out right now, there is a diffuse feeling
of opposition in me, that I have yet to fathom.
If you take it in small steps, I will be with you. Megapatches would
be an issue for me.
