I would like the cam module to be able to record in a continuous loop tape style arrangement, like this app:

It does embed into CF fairly well, but it would be nice if CF could do the job natively and hopefully manage the CPU usage a little better so that it doesn't interfere with satnav and music playback.
(I've gotten that app down to 68% CPU usage with the right codec and frame rate, it almost works perfectly with CF, just makes the satnav voice even more likely to stutter)
