In my personal experience, that still allows kazaa clients to download
files. Uploads are prevented, and that's a good thing if you're
committed to stopping p2p traffic. However it's only half a solution.
The reality is, fighting p2p traffic is a losing battle. I suspect
that's one of those things that will have to be addressed by corporate
policy/enforcement and with host-based restrictions (don't let users
install software on their own boxes).
