Barry,

I know that is what they are selling.  I guess that I was a bit obtuse on what
I was saying.  At the X Technical Conference, Mike Braca of Visual Technology,
Inc. informed us why we should all change the way we write X applications.
Most X applications (especially Xt based applications) are so intensive of
server resources.  That they cause an X terminal without virtual memory to
run out of resources.  His opinion was that changing the way we program was
the way to fix this problem.  The rebuttal was that changing the way X terminal
vendors implement their systems is a more appropriate way to fix this problem.
This requires either X terminals with virtual memory or with massive physical
memory.  Virtual memory X terminals are or will be available shortly from
most of the vendors.  But it is very unlikely that a CHEAP X Terminal with
very large physical memory and no virtual memory will be available soon.

Am I being slightly clearer than mud now?
