Theoretically seamless and easy P2P file sharing. Add “http://edn.redswoosh.net/” to the front of a URL, and it’ll go through a P2P client instead of being served up by your HTTP server. Kind of similar to what OpenCola were doing in 2001.

Distributed P2Pish secure backups. You give up 10Gb of your hard drive, for the rights to distribute 1Gb of your files across hundreds of peers. Sadly Windows-only, and there’s no way to tweak how much *bandwidth* you’re willing to give up, but could come in handy.

Interesting attempt to add more social context (eg. trust, recommendations) to BitTorrent donwnloads.
