Just a quick thought, wouldn't caching peer to peer end up being a
massive cache full of illegal files and small amount are not worth
caching
Eg user downloads a linux distro over peer to peer, uses 500mb+ which
you cache but not many other people download this so its 500mb sitting
there cached
Then you have a number of users downloading the latest song from a
certain band, you cache this and it stops 100 downloads of a 3mb file
Plus sides being users get fast download speeds, ISP may save on
international bandwidth
Downside is ISP needs terabytes of space for the files, most of which
would be illegal and the ISP would be acting as an illegal file server?
As much as it would save on international bandwidth costs, the
legalities around it would be massive

Subject: [nznog] Caching peer-to-peer traffic: a done thing?
I'm updating my labnotes for my network management paper regarding the
use of proxy caches, and previously I have pointed to the possibility of
caching peer-to-peer traffic as shown in the paper Deconstructing the
Kazaa Network
http://portal.acm.org/citation.cfm?coll=GUIDE&dl=GUIDE&id=837393
I would like to know whether or not caching of peer-to-peer is something
that ISPs actually do today, and if not why not. I imagine there are
probably some interesting legal interactions, but I'm eager to find out
how industry is moving in this field.
