You'd have to email customer support to get an answer to that. The "official" line has always been that Cakewalk does not allow re-selling of licensed software, however it has been acknowledged that EU regulations prevent companies from imposing such restrictions.
There is currently no mechanism in the user account system for a user to make such a transfer, so it would have to be on a case by case anyway, which requires contact with Customer Support.
Sorry I can't be more helpful here.
