Greetz all, been a while...

I've been looking around for different ways to keep users on a network from using Kazaa. Most of the users are knowledgable enough that if I manipulate the stations themselves, they'd change it back or work around it. I'm looking for the silver bullet, so to speak. I want to block it at the gateway (OpenBSD box).

Although I've seen quite a few threads here and there on the subject, no one seems to have come up with a difinative answer on the matter, and I was wondering if any of you have figured this out. Pray tell!

Thanx a mill!
