Now that there's ArrayBuffer will a binary protocol be added? https://developer.mozilla.org/en/JavaScript_typed_arrays/ArrayBuffer
Just need to say you're using the binary protocol in the handshake. Don't need length or anything since it would just be a normal TCP stream and someone could create their own sub protocol. Been waiting for a binary protocol for a while for games. Send would just accept an ArrayBuffer and treat it like an Uint8Array probably. If you said you were using a binary protocol then the onmessage event.data would just be an ArrayBuffer object. Simple. Please don't make it complicated. Don't be like "but people will get confused when their long messages are split between multiple onmessage callbacks." It should just be a pure TCP stream with no special stuff. That is you could get any amount of bytes during a receive just like regular TCP where anything over the MTU is chopped up.
