	Unless, of course, you wish to _eat_ by selling what you write
(my .sig ins wholly unambiguous).  The Free Software Foundation makes
it clear that they do not want, and can leagally prevent you from, 
using their software for commercial software

	I wont argue this point with someone whose .sig leads me to
believe he is a professor of computer science ;-).

	Some in this thread have mentioned specific platforms which 
will not support X server software.  However, I do stand corrected,
as my X11R4 server is 704K (What did you do to make it so big?).

	However, it is much cheaper to purchase commercially developed
software than to hire a programmer to support it.  We are talking about
biologists, and I don't think too many biology-related curicula require
the coursework or experience needed to support such systems.

	Never said it did.  I'm just saying that I believe they have
a better approach to running a unix-like system than others, and I 
wish that UI and OSF would make creating this type of system a 
priority.
