Dirk commented on this earlier. CC cluster is written in Visual Basic 
and runs on Windows. It has serious memory and resource limitations 
which prevent it from keeping tables of user/ipaddr data. This applies 
to ALL CC cluster nodes, not just VE7CC-1. His node is particularly 
vulnerable since he has 800+ Users on a contest weekend. This is a 
significant number of users.

However, considering the attack this past weekend it is better to dump 
these spots than have to deal with crashed nodes and logging programs 
that a spot flood attack will create. Some nodes that did not crash were 
15 minutes behind delivering spots to the local users.

THAT was the equation. EXISTENCE!... SURVIVAL... must cancel out... 
programming!
