The vast majority of our last-mile connections are fixed wireless. The design of the system is essentially half-duplex with an adjustable ratio between download/upload traffic. PTP heavily stresses the upload channel and left unchecked results in poor performance for other customers.

I would be much happier creating a torrent server at the data center level that customers could seed/upload from rather than doing it over the last mile. I don't see this working from a legal standpoint though. Why not? There's plenty of perfectly legal P2P content out there.
