It has been my understanding that running xgrass requires a Motif runtime
license to run *legally*, although it doesn't access Motif code
dynamically at runtime. That was posted to this list or grassu some time
ago, and I had the impression that it was pretty definitive -- maybe it
wasn't. Could somebody clear this up, please?

This is another item that keeps getting conflicting coverage. Simon, do
you just circumvent the GRASS anti-concurrent-user locking mechanism by
brute force, or is there a more elegant means that you might share -- I'm
supposed to be setting up a lab here too, on an existing 486 base.
