About Lightworks: I look forward to test it and follow it, especially when (if ever) it will become open source. I'm not a fan of companies using the term "open source" just to gain publicity, without understanding what it really means. Good integration of ffmpeg/ffmbc in the OSS version could undermine their commercial version for many, but again, $60/year is nothing for commercial use, and I don't mind it. I agree that Lightworks, open source or not, can help with adoption of the Linux platform.
