[ardour-dev] ardour video track

I've succeeded to "overlay" a video-timeline with gjvidtimeline.sf.net
(svn version always-on-top over the ardour editor window)

to sync the zoom level & scroll to ardour's editor canvas I use OSC and
a simple patch to ardour. - in order to complete the patch I'd need to
hook into ardour's visual_changer and add some config variables..

so here's the Question before I start coding: is there any chance to get
sth like this merged into ardour-svn ?
