MicroXwin ?

"MicroXwin is binary compatible to the Xlib API. However it is niether
client server nor network oriented. Graphics operations are
implemented in the linux kernel via a kernel module. An open source
Xlib library sends graphics commands to the kernel. There is no
network overhead and no context switch from X client to X server. This
makes our solution smaller and faster than traditional X Windows."
