Heeey.... that actually sounds quite workable. Never tear down the 
ringbuffer and never stop recording if you don't have to.
Of course you could add all kinds of options that would for example stop 
recording LiveTV if you're not watching it for a long time but that's 
just details.

Sounds nice, but  thinking of a good interface that makes this easy for 
the user might be a challenge maybe?

I would already be happy with the first part of your suggestions!
And I'm sure I would be just as happy with the second part if I would 
ever get more than one frontend :-)
