I think DVDRW drives will dominate even if they're slower. To fit a dvd movie on a 2Gig disk, it will still need to be compressed, and it won't play in a DVD player. I realise that not everyone is a pirate, but people tend to go for the most flexible solutions. This is a proprietary format, that I believe Sony and possibly other companies have an alternative to. For you to share files with this format with someone else, they'd need an identical drive. You're data storage is also dependant on this format succeeding, and your drive not dying. It does sound promising though.
