Online games stealing your bandwidth

There's some standardization work being done in the IETF ALTO working
group.  They're looking at ways ISPs can inform P2P clints about which peers
are "better", I.e., topologically nearby.

I'm less familiar with DECADE, but I believe they're working on more
directly cache-related stuff.

I once read an article talking about making BitTorrent scalable by
using anycasted caching services at the ISP's closest POP to the end
user. Given sufficient traffic on a specified torrent, the caching
device would build up the file, then distribute that direct to the
subscriber in the form of an additional (preferred) peer. Similar to a
CDN or Usenet, but where it was cached rather than deliberately pushed
out from a locus.

Was anything ever standardised in that field? I imagine with much of
P2P traffic being (how shall I put this...) less than legal, it's of
questionable legality and the ISPs would not want to be held liable
for the content cached there?
