I know the software exists to at least change your on-screen name: the Nightsquad message board uses it. You keep the same User Name to log into the system with, and that will always be the name the system tracks you under, but you can change the name that appears onscreen. (Proton Charger uses the heck out of this feature, changing his onscreen name just about every day or so). It'd be up to Chad to implement something like that here, of course…
