Cool... that's an interesting project.

I've let our webmaster know about the problems you had and he'll try and
address them shortly.

Currently X11 is required for 2 reasons:
1) OpenGL acceleration. Essentially, to get good OpenGL driver support
you have to be running XFree86 4.0 with DRI. We plan to move away X
(mainly because of it's large memory/resource requirements and our
interest in wearable computers), which will probably involve SDL or GGI.
Currently though, these don't offer the same level of hardware
acceleration as X/DRI.
2) Support for regular 2D applications. This is achieved by running X11
(either locally or remotely) and displaying the X desktop in our 3D
environment using VNC. You can an example of this on the screenshots

We aren't using ORBit (which is what gnome uses), instead we use
omniORB. We haven't looked at security too much so far, we are still in
the initial stages of building the UI. Can you give an example of what
you are proposing?

Hmmm, that shouldn't be in the requirements. Where did you see that, I'd
like to fix it. You only need cavelib if you are actually running in a
We haven't done any testing on an SMP system, however I believe it will
beneficial. 3dwm uses a threaded client/server architecture. The server
is responsible for rendering the 3D environment and the client(s) are
responsible for generating the world content (building the scene graph).
I think this should scale nicely on multiple CPUs.

Our mistake, it will run fine without cavelib.
