I'd also like to respond, as if their BS actually needs to be taken seriously, that I have personally never had a Win32 application under Wine crash my Linux kernel, nor have I experienced a Blue Screen of Death while running an application under Wine. For me, that pretty much negates the "market advantage" their alleged architectural improvements supposedly gives them over Wine.
They say they're giving a demo of their beta version to the press today, so perhaps we'll have more specific information tomorrow.
Incidentally I wonder how Bill Joy would feel about his words and name being misused as a virtual endorsement of this company in their marketing spiel.
