I'm somehow puzzled by the requirements and can't really imagine that all of these are really needed. Then again, I'm rather new to this and have never actually used a Linux- or BSD-based OS; I'm interested in trying this now, however. I'd also like to see this desktop environment in PC-BSD, since it seems to offer a familiar look for a former Windows user.
