[c-nsp] Dealing with bit torrent and other P2P applications

[Brian Turnbow]

cisco doesn't have a pdlm for bittorrent. it would be nice.
You can however use a custom pdlm and block .torrent files and the standard
port numbers.
If you have the time you can analise bittorrent packets and try and find a
pattern .
If you do please post it.
regards

Brian
