Also somewhat OTish but pertinent is this article.
Good link, thanks. But it shows a big difference in apps: FCP (and Vegas) are't meant for real time (or near real time) simultaneous editing & collaboration. They're meant for the "one man army" approach. Nothing wrong with that.
I think it was Fractal/Corel/Whatever Painter that did the same thing as avid: let multiple users (via network, local, WAN or internet) work on the same thing @ the same time with real time results.
That would be a killer feature for Vegas to incorporate. Don't know if they could at this point, but it would be awesome!
