Actually, both cookies and ? URL's can be used to maintain state in run
of the mill http+html.  Your can encode your data in either, or just
encode a database key in either and have the server look things up in a
database under the key.

Also forcing frequent reloads works fine with your usual http+html,
though you could come up with a browser plugin that would be more
efficient.

If you restrict access, and refresh every 5 minutes or something, I
doubt you'd have a load problem.
