Interesting idea TD&H.
My feeling is a DVD of the Mag Men film wouldn't get great sales - the video is / was avaliable and most fans would have it.
BUT if produced as a limited edn WITH Shuttleworth content, as a fund raser for OW; then it might just work. Shiuttleworth might be able to get the rights for that limited version, while no company would be likely to release the full region 1 / 2 version on the open market (though I might be wrong.) And yes, I'd buy one!
Cheers
