You're kidding, right?

You also forgot to mention that when you use "unstable" to delete a
recording, then when you switch back to "stable", it will still expect
to find the recording there (because its copy of the database still
has it).

So now you have to make separate copies of all data pointed at by the
database (recordings, music, videos, photos). You can be fancy and
make hardlinks or something.

But at this point, all you have are two separate instances of MythTV,
with not much "switching" between two different branches of code ...
