I hate to break this to you but some P2P systems are now using encrypted 
SSL sessions on port 80 or 443.  These are pretty much indistinguishable 
from web traffic, even to a packet inspecting IDS (its encrypted, so the 
IDS can't peek at the inner content to say "this is HTTP is its OK" or 
"this is P2P so its bad").  The arms race moves on... :-)
