	I have an endless respect for your courage. Not only you would
	have to make the MIT server compile under VMS, but you'd have
	to hook into VMS-specific transport mechanism, used by VMS flavor
	of Xlib (local==shared, DECnet, TCP/IP, LAT ...).
	Plus you can expect about 5 times worse performance.

	On the other hand, VWS 4.1 includes an option to run DECwindows
	on the top of VWS(UIS). The DECwindows server gets a UIS window
	covering the entire screen, and you can run both UIS applications
	and X.
	Yes, it's a memory hog, but the performance did not seem to be
	much worse than the "native" X. The initial version was "unsupported",
	i.e. buggy and unreliable, but I believe the current status has
	been upgraded to "supported".

	In addition, DEC is readying the UIS emulator under DECwindows
	(demoed at DECUS). I believe they can be done sooner than you
	- even considering typical VMS Digital has it now (when can
	I get it -) .
