MetaPlace is not an MMOG. It's a platform for creating virtual spaces that can be used for anything the creators can imagine. As such, the traditional MMO EULA is completely inadequate. Raph Koster - the head honcho on the MetaPlace project - made that clear in a panel at AGDC08. So, the folks working on MetaPlace had to come up with a whole new set of rules - rules that allow users ownership of their virtual property, for example. There's a veritable landmine of problems awaiting this endeavor, of course. That's not to say it's impossible. It's just going to be extremely challenging.
