Is there any easy way for code running on a frontend to get the proper
hostname of the master backend for use when saving information to the DB
where you have to set the hostname to the backend name, not the frontend
name?
Thanks,

This problem presents itself in almost every distributed system. The solution I've always employed is to have the "master" backend, database server, load distributor, etc. broadcast a "beacon" via UDP to a particular IP subnet. As various "slave" machines (horrible nomenclature, but not mine. No flames please.) are attached to the subnet they listen for the beacon and determine the address of its sender.
I'm not sure whether MythTV employs such a beacon (perhaps MythTV has employed a better solution that I'm unaware of), but implementing such feature is relatively simple. When I get a MythTV development machine, I may even try implementing it.
