I have, on occasion (twice now) played a cut thru iChat AV from my DSR-11 deck. A the same time I was on the phone with the producer (who was in Hawaii) who gave me notes.
But…again…both parties need a mac.
Most the time I do what Walter does…post my cut on my iDisk with TC for producers to view and give notes. Beats running a DVD over with every change….
