Isn't a chunked stream the anti-thesis of RPC? It looks like you're acknowledging WebSockets works while asking about what to do with current web infrastructure. It seems to me that current infrastructure is -mostly- Flash based and assumes a level of control over input: one can't send arbitrary information as a developer.. It has to be directly from a webcam or similar media stream.

Do you have specific examples of existing infrastructure you're hoping to support?

And MediaStream/Stream, which has to so with your request.
