This question belongs in comp.windows.x.

MIT-SHM is an extension to the X window system protocol which is
handled by the default configuration of the sample server from MIT
(and probably other vendors' servers, too).  You can find out about
this by typing `xdpyinfo' to your X display:

	...
	number of extensions:    4
	    SHAPE
>>>	    MIT-SHM
	    Multi-Buffering
	    MIT-SUNDRY-NONSTANDARD
	...

The MIT-SHM extension provides a fast transfer method for pixmap data
for clients that run on the same machine as the server.  I don't know
about any programs that use it, but SHM should be beneficial for
animation programs or so.
