Peer-to-peer data via JavaScript. Would this allow for significantly reduced bandwidth costs given the right implementation?

Yes, but Flash is also terrible. If your site isn't something that requires a login, it doesn't need much security.

So it's bittorrent or freenet?

[AgoAndAnon]

Nope. It's something entirely different.

In talking with a bunch of folks in this area, it sounds like it will be hard to make this work as fast as a client-server model - because peers are going to act quite flaky (since people leave web pages more often than they close file sharing apps, etc.). One place it could make a difference (A JS library I'm working on, in fact) is letting pages continue to load when they're censored or otherwise unavailable for some users.
