"I often wonder whether it would be possible to resurrect Unixware."
That is one of those things that may well be possible but is also dangerous, painful and ultimately unrewarding - I'd put it in the same category as going quail hunting with Dick Cheney. It looks as though you can still buy it, although I really struggle to find any upside to purchasing a neglected zombie cash cow.
"I would love to see a real genetic UNIX available again"
Depends on your idea of real I guess... I count the *BSDs as being more real UNIX than the various commercial hacks of SVR4 - but that is because I cut my teeth on SunOS and was then savaged by rabid Solaris boxes. Those boxes running early cuts of Solaris were so unreliable, and so badly set up that I concluded that they weren't running a UNIX.
Those scars linger on - as a result I still avoid SVR4 when given an option. :)
