As I understand it, MythTV needs to listen on all interfaces for a 
properly-functioning UPnP implementation.  Therefore, MythTV should be 
allowed to choose the most-efficient route to use for communication.

Since you're patching MythTV to add non-standard/unsupported features, 
anyway, why not just add another patch to remove this change--since it's 
appropriate in our configuration, but it breaks your 
listen-on-one-interface-only custom feature (therefore, removing it is 
just another requirement of your custom feature).
