Im doing a live performance, using vlc with webcams and lcd screens/
projector, pd objects for dsp and ardour for playbacks and miditracks.

Vlc usb cams shall be synced with pd audio.
The singer shall be shown over projector, means lips have to be synced
to audio

If i go on netjack, which is already planned for ardour, would it work
to send an audio sig to VLS, which syncs all video to the received
