RFC: GIT networked storage

Here's an experiment I've been dying to try.

The current "tracker-less" BitTorrent[1] employs a distributed hash table[2] called Kademlia, where the total content is spread across a bunch of computers on the network. I kinda prefer TANGLE[3] to Kademlia.

Anyway, I was thinking that it would be a neat experiment to add simple TANGLE-like peer-to-peer code, to enable git to query "the git network hash table" for content.

Comments, or any pre-code-creation objections? How easy is it to add a new storage backend to git?

To restrict unlimited uploading, I'm thinking that I'll want the system to fall back to {www,git,rsync}.kernel.org as the original source of content. [though the code will obviously be generic, and not hardcode *.kernel.org policy]

Thanks,

	Jeff
