Nor have I. Note that I didn't say "degrade". I said live with "slightly lower speed". It's a tradeoff.

Just to be clear here, "BitTorrent" in your list is a single BitTorrent tracker which happens to be run by BitTorrent.com. It is not representative of the BitTorrent communities of which I spoke, namely the ones that are inundating ISPs.

That is quite possibly true; it is also not relevant to what I said. I was speaking about the BitTorrent communities that are currently the bandwidth problem for ISPs; you are speaking about other p2p communities whose current bandwidth usage is probably at least an order of magnitude less than the ones of which I am speaking.

Of course, in the future, the bandwidth market may shift towards the kinds of systems you are talking about. If so, Alto could very well be helpful. People clearly want to work on that future problem, and Alto might be a good place to do it. My expressly-stated concern was From alto-bounces at ietf.org  Fri Nov 14 17:25:39 2008

People clearly want to work on that future problem, and Alto might be a good place to do it. My expressly-stated concern was that thethat the problem statement document has wording that makes it sound like the Alto proposals might have an affect on the current large amount of traffic, which I believe it won't.
