If you have the MySQL server running on your SlaveBE I dont see why you 
can't just make a new mysql.txt and have the loopback address in there 
(127.0.0.1) now just switch the files

cp mysql.txt.nework mysql.txt
cp mysql.txt.local mysql.txt

Just to be clean you can even create a rule in iptables that will block 
mythtv and mysql from talking to the network when you are switched to 
the local state.

To me this looks like you could make a nice switch-to-local script run 
it then just import the recordings.
Anyone know if you can script the mytharchive import program to fine the 
recordings and import them into the database?

If you get anywhere with this I would love to see it or even help.

Thanks
