As someone else pointed out (sorry, I've lost that email so I can't name
you!) the CORBA implementation we use (omniORB) should talk to the
ORBit, although we haven't tried it. 

We also haven't looked into security much, although implementing
something along the lines of xauth and xhost would be a possibility.

Support for multiple displays is a certainty. Essentially the CAVE is 4
separate displays and stereo 3D glasses are 2 displays. It comes down to
implementation issues, i.e. will the current OpenGL drivers work with a
dual monitor setup, if that is what you want.

3dwm is a fully distributed client-server architecture. The server does
the rendering but the client can run wherever you want. Additionally you
can have an X desktop displayed from anywhere via VNC. There is a lot of

We don't actually do any dedicated 3D, everything is via OpenGL. That
means we get acceleration with X11/DRI, but fall back to SW rendering
outside X for now.
