Is there any chance that you chould post the hi-res movies at a site to allow downloading for us intreeged individules? Perhaps download.com e-donkey or something like that?
Yeah you don't have host the files yourself you know. I'm sure someone would volunteer (not me) to distribute them with some kinda peer-to-peer program like bit-torrent. Download.com would probably charge you and e-donkey isn't appropriate.
