What options does a web developer currently have for implementing client-side peer-to-peer systems in the web browser? Some hypothetical examples might be a file-sharing service that bypasses the web-server after clients find eachother, or a chat service.

What I know about:

• the site chatroulette uses some flash technology as discussed here.

• And I am also aware of Opera Unity which extends the browser model to encompass both a client and a server, as well as this firefox plugin which works similarly

• I also just came across this blog post related to the Joose js framework, but am not yet sure if it is relevant here.

• Support for this kind of thing seems like it might or might not be supported by websockets in HTML5 and has been discussed here and here and here.

I recommend you to take a look at RTMFP protocol in Adobe Flash Player - it seems you can build something close to what you're asking with it.

I was looking for the same thing, this library looks apealing: rtmfp-api/
