jit.qt.movie and elastic~

I would like to use jit.qt.movie with time-stretching.

For time stretching I would like to try the commercial elastic~ object because it’s easy.

It seems as if you can get audio from jit.qt.movie into msp using spigot~. spigot~ just creates an audio file so I see no reason why a buffer~ object could not reference the same file.

This being the case, how would you get jit.qt.movie and elastic~ to play in sync?
