It would be nice to have a list of use cases for why anyone would want
a Web page (as opposed to an installed client or client extension) to
provide two-way communication, and also why that two-way communication
must be tunneled over the Web ports in a way that deliberately intends
to fool security-enforcing intermediaries into thinking it is HTTP.

I know that Netscape and Macromedia/Adobe and MS have provided various
such features (and their associated security holes) over the years, but
I've never found the need to copy them within a Web page.  It would be
nice to put the rationale out there before the protocol.
