When I see a modder with a lot of drive that has done something cool, I tend to contact them. I shot him an email recently asking if he was interested in exploring an opportunity here. As to what comes of that, who knows -- that depends on the mutual fit and his own goals.
Regarding this trademark/copyright business, I don't know because I'm not a Blizzard employee, but I seriously doubt this is anything other than the fact he named the mod World of Starcraft, which has an air of legitimacy that borderline infringes on Blizzard. Blizzard is very supportive of their modders, but also vigorously depends certain aspects of their IP (as they should and must).
