I second what Sebastian said -- glad we could revive Wikivideo-L to have deeper technical discussions like this that don't annoy the multimedia-L list.
When I have more time, I'd like to test our more of what Brion said. The solution may be right under our nose with older, but tested, solutions like MJPEG/PCM, though we'd still be requiring pretty fast bandwidth to deal with them.

Apparently the US Library of Congress has been archiving videos as MXF (the container format that MOX is planned to be based off) with lossless-mode JPEG 2000 for the video payload... and they're pushing a baseline format around that for digital video preservation.
This is also the basis of the 'DCP' format used for distribution to theatres with digital projectors, so there's simplicity in standardizing that for archival of finished films.
Of course JPEG 2000 and MXF both specification with gratis distribution, but I'm not aware of any patent restrictions on implementations.
