I suspect you don't know from reading your comment, but Schell Games actually worked with Disney to make some of Toontown. Also, about old players, he says that all accounts/toons are stored in the Disney database, so old players could use their old accounts. I'm not saying this answers all of your questions, but I hope it answered some.
