LiveTV will work on any frontend regardless of which backend the tuner
is on--i.e. the tuner does not have to be local for LiveTV.

Yes, you can create combined frontend/backend machines. You can have as
many backends as you want (one primary/master and the others are
slaves). You can have as many frontends as you want. Frontends and
backends are logically separate--even if they exist on the same
machine--so you get the same result having a separate frontend and
backend as you get with a combined frontend and backend.

If a tuner is free--regardless of which backend has that tuner, it can
be used for LiveTV or recordings. If no tuners are in use and a machine
is a combined backend/frontend (i.e., it has a local tuner), that tuner
gets a higher priority than remote tuners (although this can be altered
with user-specified priorities). But, if the local tuner is not
available, a remote one can still be used.
Even if a combined frontend/backend is in the process of recording
something, the frontend can be used for something unrelated to the
current recording (i.e. watching a DVD, a video, or a
previously-recorded program). I never watch TV while it's being
recorded (so I can skip commercials and playback at
faster-than-real-time), and I only have a single combined
frontend/backend, so it's often recording shows (sometimes multiple)
while I'm watching a previously-recorded program.

Instead of moving the already-in-progress recording, the frontend will
simply request the services of an idle card.
