I find myself wondering that too.  Could myth protocol use UPnP or XML
for everything except the parts that cause the highest CPU load and/or
bandwidth?  Or how about enhancing Mythweb (random idea: use AJAX?)
and make the front-end interact as if it were a web browser?

At the risk of throwing ideas in too soon, hopefully any
authentication would allow for multiple simultaneous users, as well as
allow for restricting access/permissions for each of those users (not
only restrict which menus, but also which groups of shows are allowed
or disallowed).

Looking around, perhaps DPWS
(http://en.wikipedia.org/wiki/Devices_Profile_for_Web_Services) could
be used?
