Hi,

jack_capture is able to do exactly what you ask for.
jack_capture is mainly made for recording audio,
but to avoid recording anything, just run it in "timemachine"
mode:

$ jack_capture --meterbridge --timemachine --port system:playback_1 --port
system:playback_2

(make sure "meterbridge" is installed)
