PeerApp provides ISPs with P2P caching systems

The Jerusalem Post has a very non-tech article on PeerApp, an Israeli company which provides ISPs with systems to cache popular files for P2P downloads inside their networks. The company's website has a few more details; apparently, they sell systems to ISPs, which cache locally the files P2P programs request, and then redistribute them to subsequent requesting peers. Their products support a number of popular P2P file-sharing protocols, and intervene "transparently" (so they say) in application-level communications.
