It's a great editor but it's not an easy editor. The interface (colors, widgets, etc) also turn some people away. I've used it off and on since its Broadcast 2000 days.
I've heard about this a while back, I've yet to hear anything about it. Linux isn't for the faint of heart and you need a good solid dual processor computer for it. I could easily take advantage of the renderfarm idea but setting that up is a lot harder than and isn't as useful as people think, especially if you're trying to do so with different hardware setups on each computer. The good thing is that it's free but the bad thing is that it's Linux and everyone else is used to the PC stuff. I'd try it but I don't have my copy of SuSE Linux here with me and it's the non-64-bit version too =P.
