When a frontend is using a backend's tuner, the master backend does not 
allow another frontend to make use of it. The master keeps everyone civil.

If you are watching Live TV, and a program is scheduled to be recorded. 
Assuming you are all out of free tuners, the master will prompt you to 
give up the use of your tuner, to allow the recording to proceed as 
scheduled.

This is not a problem assuming you have enough network bandwidth and 
hard drive I/O.

Not sure on this one. I have never tried to do it. I will have to test 
this out. I assume the master backend would also prevent the programs 
from being deleted while it was in use.
