Often there is no alternative service providers to turn to because of monopolisation of the market.
Heh 'not many' o rly

You've been able to do P2P throttling with Ciscos for a while using the NBAR features. Nothing brand new there. Most people prefer to use the Ellacoya / Packeteer / Sandvine / Allot / PCube gear though for more granularity of control and because it takes its' toll on the routers asking them to look deep into packets.

The big 3 cable operators in Canada all shape, Plusnet here shape immensely, Pipex do a bit of shaping, as do BT.

No doubt there are others that we don't know about because they're more subtle

Suggest you check out Diffie-Hellman key exchange, TKIP, and asymettrical cryptography

The only way to stop a reasonably implemented encryption scheme is to use session / connection based throttling. There aren't exactly many applications that open as many connections as quickly as a P2P program
