	The money we charge pays for our software development efforts,
	support, distribution, etc.  No one pays MIT royalties for X11R4.

	You can get an unsupported X that you have to port, compile,
	fix, support yourself over the net from MIT.  You can get
	an already built, ported, supported, (mostly) fixed version
	from SGI.  Note that as we move from NeWS to X the price of
	the X dev package will be coming down.

	If you ever want to get fixes/support/working code from sgi
	then buy ours.  If you want to muck with the source yourself
	and are willing to support it then get it from MIT.
