I think I'm going to have to agree with Isaac on this one. Especially the idea
of exchanging the protocol version at the start of the exchange, I guess to a
degree the same idea as storing the db schema version in the database. The
only time I would think backwards/forwards compatibility would be with some
sort of embedded device setup for the frontend and I don't think MythTV is
really at that point. Not that I don't think it is a mature solution, it's
just changing so fast that it wouldn't make since to be stuck with out being to
I dunno just my thoughts at the moment.
