An if I had a 0.0.0.0 setup, I wouldn't NEED slave servers.  That wouldn't be an issue.  Again, this should be really simple.  MythTV Master backend could allow ALL if NO slaves.  The moment you want slaves, must remove the ALL NICs config.  An it could all be configured thru the gui they already have.

I don’t think you need the virtual network, just configure mythtv to listen on one of the IP’s then configure 3 DNAT rules to forward the ports from the other IP address to the one mythtv is listening on, you should’t need to worry about the return traffic as you have direct routes to both networks.
