Final Cut Pro can already basically do that, and has been able to do that for several years. Just create a multicam workflow and tell it to synchronize by audio. Not sure how well it works if you're dealing with hundreds of short takes though; I've only used it to line up hour-long continuous shots.
Then again, as cheap as storage is, I'm not sure why anybody actually stops the cameras and audio recorders anyway. If you want to have a private conversation, you can always step off the set and do it in a hallway or whatever.
