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
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.
