I started out thinking about how to do this with AJAX, etc, but then I
realized, "Why not run SSH on port 80 or 443?"

That should work perfectly against a simple firewall with port
filtering.  A proxy with SSL support can be got around by a CONNECT
request.  Only if you're fighting some sort of traffic classifier would
that not work.

If you are, but it still allows SSL you could use openssl s_client to
connect to a Telnet server on port 443.

Perhaps you could find an implementation of RFC 3093 (IP over HTTP).
