Hi, Chris,

Agreed. We're at about 6:1, and can almost get away without bandwidth
managing of any sort. But as you note, we do use our Packetlogic to
block P2P applications except for those registering to opt-in. The
Packetlogic is pretty good at permitting game updates while blocking
general P2P downloads, too.

We did consider switching to a share-and-share-alike device over DPI,
but kicked the can down the road a couple years before making a big
change. If you're really crimped on bandwidth, DPI makes more sense. The
main reason for our delay was the lack of a suitable box to identify P2P
separately from the bandwidth manager. We're watching the developments
in next-gen firewalls carefully, but likely won't have to commit until
several years from now when they get even better ;-)
