I would agree with the other assessments of deploying Snort and it's
rulesets to look for P2P and IM. (see p2p.rules, chat.rules, and
policy.rules)
P2P and IM both have default ports (5190 for AIM, 5050 for Yahoo are a
couple examples) however, I have seen P2P and IM run on any port.
Basically, it finds a way out. So just relying on looking for
<i>a</i> particular port won't help you in this case.

Probably one of the simplest and cheapest things you could do would be
to sniff data on your network for certain ports. All the P2P software
use unique ports, get a list of say the top20 P2P networks and their
ports and you'll probably the get results you're after.
If you have an IDS you could configure some signatures to alarm on per
port/per session traffic.
