Assuming we'd develop a WebGL viewer more or less from scratch, this
wouldn't be a problem [for the WebGL viewer]. We can separate protocol
from rendering engine from [programmable] UI.
Being able to use the Linden viewer as a collaborative authoring system
for multi-user 3d content for the Web would be super cool. [Note to
patent trolls lurking on this list: I said it here first]

Yes, Unity3D is definitely a good reference point. I find it lacking on
only two things that I think are superior in the Linden system: (1) ease
of creation: prims are easier for simple things; (2) collaborative
authoring: creating a complex scene/game with multiple developers in
Unity3d is a pain in the neck. So, we could borrow a few ideas from
Unity3D and add them to the Linden viewer -- things like specifying
camera movements, controller objects, 2D UI, etc. Even if these things
are not runnable in the Linden viewer itself, they would run in the
WebGL viewer. So while developing, we could run both the Linden viewer
and a web browser pointing at the sim.
I want this to happen. I just don't know anything about rendering, so
I'm useless wrt developing a WebGL renderer, and I'm waiting for the
hero who does that in open source. But you can count on me (and I'm sure
others here) to jump in on everything else -- protocol, authoring
