Thanks Jeremy! Interesting approach... The Xephyr part is neat:
Although on debian you need to compile ffmpeg for x264 support, so maybe 
one might as well compile it with jack?

Here's my one-liner for ffmpeg.

ffmpeg -f jack -ac 2 -i ffmpeg -f x11grab -r 30 -s 1280x800 -i :0.0 
-acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 
output.avi
