All in all I guess its not really so revolutionary.  Most of the
muds I have been involved with in any way have always been room
based. So, in a sense, I feel its a bit different.

Its not really an RDBMS in general that I think is helpful, although
I believe any solid data driven system should have some type of DBMS
(be it ODBMS, RDBMS etc) backend. I believe it is Mnesia, Erlang's
built in RDBMS, that will be helpful. I attribute this two three
things:

  1) Its tight coupling with Erlang itself, i.e. the query language
  is Erlang, and all the data types are Erlang data types.

  2) Its (optionally) RAM based, which makes it very fast.
 
  3) It is inherently distributed, which should provide for some
  real flexibility and scalability.

I would say the primary advantage for Mnesia is the tight coupling,
although the other two are a very close second.

I have looked over this in the past, but since that time I had
forgotten about it. Thanks for pointing it out.
