As for "its unique ability to run Linux® software titles as well as many popular Windows® (Nasdaq "MSFT") software titles"... so what? My Mandrake based box can do that just fine using Wine.
They appear to have forked the Wine Project, then added better/different font handling and installation.
It probably is "marketable" but that's the problem, really. They're selling "their" product based on Wine OSS, and no (on their website) reference is given to where it comes from. Typical marketers "look what we make" bollocks when it's really just tweaking or relabeling, someone elses work.
