Take a look at QNX, from Quantum Software Systems (416-591-0931).
It has a small (150K) kernel, can be distributed across multiple
nodes with transparent inter-task communications and file acess
(it's message-based), will have a GUI (based on Open Look, but without
X) this spring, will be Posix-compliant this summer, and is very
fast (it's well-known in the real-time market, but a sleeper
otherwise). Personally, I think X Windows and real-time are mutually
exclusive. That's why the QNX implementation is native (so the server
requires only about 300K of RAM and has numerous real-time extensions).

bias: I am associated with Quantum, and wrote a book on QNX.
