Ask HN: decentralised P2P website mirroring?

The recent case of Wikileaks being booted off AWS provoked the following thought: if lots of people started mirroring wikileaks on EC2, Amazon would be forced into playing whack-a-mole to stop it. Game over: the revolt of a user-base, the inevitable collateral damage, etc. leads to bad PR and (hopefully) reform and vertebrates. Amazon's nice GUI combined with their introductory offer making a micro instance basically free for a year, means that putting up a how-to page/YouTube video showing every college kid with a credit card how to do it can't be too difficult.

My question is, what next? How to you turn a swarm of small, transient mirrors, potentially not just on EC2 but all over the 'Net, into something findable and load-balanced to deal with the (potentially) huge demand of serving Wikileaks traffic?

Therein lies a problem. Round-robin DNS load-balancing with a very short TTL is one obvious approach, but this begs the question of how one boot-straps and then maintains the CNAME record containing the list of mirrors. The stable domain could be a CNAME to DNS servers that are themselves part of the mirroring swarm, if each node acted as both a DNS and an HTTP server. Each node would return a randomized list of the nodes in it's neighborhood.

Apart from that, I'm not much further along in my thinking. What do you think about the feasibility of the idea?
