javascript - Will HTML5 allow web apps to make peer-to-peer HTTP connections?

Question

Is it possible to create a web app that, with the help of a central server, could create direct connections with other users of the same web app? I'm imagining a process similar to UDP hole punching.

I've read about the new WebSockets API in HTML5, but it appears you must initiate the connection with a WS-compatible server before the fully-duplexed connection can begin. I'm thinking moreso about a process to make direct connections between clients, with a server getting involved only in the initial handshake.

NOTE: Java applets don't count. I'm interested only in standard browser technologies.

Answer 1

Instead of intelligent guesses, here is an informed answer:

HTML 5 plans to allow peer to peer connections from javascript, but these connections WILL NOT BE RAW TCP.

The complete spec can be found at http://dev.w3.org/html5/websockets/

EDIT: with specific reference to peer to peer connections, check out these links:

• Regarding peer to peer connections: http://www.w3.org/TR/2008/WD-html5-20080122/#peer-to-peer
• Regarding broadcast connections to the local network: http://www.w3.org/TR/2008/WD-html5-20080122/#broadcast
• Regarding TCP connections (in the encoded protocol): http://www.w3.org/TR/2008/WD-html5-20080122/#tcp-connections
• Complete proposed spec: http://www.w3.org/TR/2008/WD-html5-20080122/#network

Its important to note that the capabilities are still being negotiated. It will be nice to be able to create "local chat" web apps :)
