I think VOS already uses the reactor pattern, more or less.  It just 
seems like a way of binding particular events to callback methods on 
objects.

I agree.  I actually want to look into the SVG rendering model as a 
basis for the 2D drawing kit, and permit rendering to texture as well to 
screen overlays.  Something else I'm thinking about is VNC-style 
optimizations for streaming bitmaps, so you can paint a continously 
update desktop snapshot onto a texture and render/interact with that.

You also bring up a good point that it is very desirable to be able to 
present different UIs to different users, even if they are in the same 
space -- which is one failing of the current A3DL model that I intend to 
correct in s5.  This is harder than it sounds, since it means that we 
now need to be able to distinguish between shared and non-shared 
per-user aspects of the 3D presentation.
