And, much to Harmy's obvious chagrin, I'm also considering uploading a comparatively small, tablet-friendly m4v to the spleen with only a few audio tracks for people who want to watch this awesomeness on the go or else want to enjoy Star Wars but don't have much HDD space or bandwidth to spare.

I started a thread with a few questions about making m4vs over here. I found that using the Apple TV 3 preset or the iPad one gets you something in the range of 4 gB if you limit it to just one soundtrack or the main three English ones. I remember h_h saying that the surround mix really shouldn't be played on devices that don't do surround because of phasing problems. If saving space is a concern, perhaps just the mono or stereo mix? (May be better to take that discussion to another thread.)
