Hmmm, now this is all very hazy in my mind, but, using jack, I seem to 
remember there is something called a time machine - google - yes here:

http://plugin.org.uk/timemachine/

and there is a silence detector for jack as well:

http://users.ecs.soton.ac.uk/njh/silentjack/

so.... could these be hooked up so that (actually you may need to mod silence 
detector to work in reverse, I will try to play with it soon) when sound is 
detected, it fires the time machine, then when silence is detected, it stops 
recording and waits for sound again before hitting the time machine to start 
recording again...
