So I think I'll keep this response short and see if I can
come up with a BWTP mkII proposal that addresses
the feedback that I've received.

An application that sends just a single content type like JSON is
not going to have any advantage from that proposal, because it
can assume that messages will be text/json;charset=utf8 and

will benefit. Also any application that might want to conditionally
compress or encrypt a message would benefit.
Also browser that want to share a single connection between multiple
WebSocket API instances would benefit as they could use the metadata
to organize the virtual connections without the need to alter the
