Ian,

you often cite "protocols layered on top of Web Socket" as a panacea.

While layered protocols are theoretically possible (and even
desirable), I do not see that websocket is being setup in a way
to make this practically possible.

So can you describe how you foresee such protocols being layered
on top?

If you think this can be done in javascript libraries, then how
do you see multiple frames, tabs and windows being handled in
a secure way?

If your vision of the server side occurs - where developers write
websocket implementations themselves (like CGI scripts), then
are they going to have to all write these layered protocols as well?
