Man... I still feel obligated to run a client when I have a new version in the rumble, but damn, once your clients pick it up, it feels pretty useless. :-) You've got me yearning for a quad core "Robocode machine" again, maybe I'll actually pull the trigger this time.
These aren't actually "my" machines... I have two servers at work that I'm not using for anything useful so I thought I would help out a little. Now that I have two servers running 6 instances each I'm trying to be the top contributor in each area of the rumble. Silly goal, I know, but it makes me happy. :-)
