Yes, that's right -- by David Abramson and Rok Sosic, a close friend
of mine. :)

Jim, I wish I had realized that David was there at Monash. When I got
up to Brisbane and tried to look him up, I realized that I'd just
missed him down there with you.

How many machines do you use?

Clustor can send out jobs to machines running NT and several varieties 
of Unix, including Linux. I'm sure that you know this, Jim, but other 
tluggers probably don't. Here's the url about Clustor:

  www.activetools.com

BTW, I have a trial CD of Clustor that I can give to the TLUG library
if there's interest.
