It does now, as of Aug 26th in fact. The BitTorrent PDLM will work on all Cisco platforms running the following Cisco IOS Releases that
currently support NBAR:
* Cisco IOS Release 12.3
* Cisco IOS Release 12.3 T
* Cisco IOS Release 12.2 S
* Cisco IOS Release 12.2 T
* Cisco IOS Release 12.1 E

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
