Note that you'll need to set it up so that the remote frontend can 
access the MythTV master backend on all the ports it uses and so that it 
can also access the MySQL server directly.  And, of course, you will 
need to provide sufficient upstream bandwidth from the master backend 
system to allow streaming the recordings (where US ATSC can be up to 
~19Mbps and, from my channels, averages ~13.5Mbps) plus sufficient 
additional bandwidth to handle communications with, i.e., the 
database--not to mention any other network use from other apps/services/...

Oh, and there's absolutely no security provided by MythTV, so be careful 
not to invite disaster.

And please make sure that what you're doing is not in violation of laws 
or provider terms of service.

That said, I'm expecting the performance will be poor and the experience 
much worse than you'd get from a "local" system.
