Looks almost okay. The URL (given to a client) can start with any of the
following,
tp://
tps://
http://
https://
tphttp://
tphttps://

Not at the moment.

The (.*) is the "game name". On servers which have only one game it can
be ignored. On servers which have multiple games it should be appended
to the username.

See above.

Do you know if tp+http is a valid name, it would be better then tphttp
which we currently use.

scheme registration process?
The tpclient-pywx registers for tp, tps, tphttp and tphttps links in
Windows and Gnome.

It'll go in the protocol4 document.

This is what the Python protocol library does. It should handle the
cases where some information is left out (IE username).
Hope this helps.
