But the key is "when legal shifts to P2P" (eg, like CNN's live video streaming), they must be able to cache it, because this is obviously coming down the pike, and spells bad news if it happens without caching.

I see your point here. But this makes me wonder if P2P caching is just a way for ISPs to subsidize P2P CDN companies -- another form of cost shifting. (Will P2P CDNs bill content providers for total bits delivered, even if those bits were delivered from an ISP-owned cache?) I suspect economics of this sort is off-topic for IETF so I won't ramble on any more.
