Has Giovanni loosened up a bit about licencing? I talked to him at a
SIGMETRICS about looking at GreatSPN -- looking, not using, evaluating
as it were -- and he wanted 5-10,000$ for it.

I suppose that's because I was (and still am) working in industry
rather than academia.  Sigh... has nobody ever heard of hobbyists?
Enthusiasts who try something out in their own time, and if it works
then persuade their company to start purchasing and applying it?
Oh well... it appears to that world that you are either in university
or industry; nobody recognizes the amateur anymore.
