Currently, it's quite primitive. It has fixed key mappings, it's pure text mode, etc, and really it was written as a proof-of-concept, but it functions, and I don't intend to work on it too much more. If anyone wants to add to it, though, feel free, as it's released to the public domain.
Anyway, you can find it here. Basic compiling/running instructions are there, but there's no fancy schmancy configure script or anything.
As for requirements, it just needs an X server that supports the XTEST extension... which encompasses any XFree86 or Xorg-derived server. Not sure about others (eg, Solaris).
