Localization was getting a little over-hyped so I like this document.
Here are some suggestions:
I didn't see any mention of traditional ISP-operated HTTP caches (not
CDNs), their discovery protocols (WPAD), and their legal status. These
may have fallen in popularity in recent years as the cost of transit
has dropped, but clearly some ISPs still use them (as you can see by
searching for "caching youtube").
This draft may want to reference BEP 22 (http://bittorrent.org/beps/bep_0022.html
) as a strawman cache discovery protocol.
AFAIK, many P2P caches available today are expensive inline DPI-based
devices due to the lack of a discovery protocol, so I think this draft
understates the cost savings possible due to a good cache discovery
protocol.
I think if ISPs really want to save bandwidth they will have to cache
as much as possible, not just "registered" legal content. IANAL but
the DMCA appears to allow this. Traditional HTTP caches cache
everything (certainly there is plenty of pirated content flowing over
HTTP), so I don't see why P2P would be different.
