Most of my information about LDAP (i.e. the fact the "in memory"
stuff, etc) came directly from the Sun reps that are trying to sell
us equipment.  I've look at it at a very high level once (connecting
to the Novell directory service) but, as I said, I'm not that
familiar with it.

In a large-scale MMOG you have to assume hundreds of thousands of
account records (and yes, I'm crossing my fingers on that one!  but
you still have to plan for it) each holding N character records.
And since we want to have one account able to log into multiple
different "game servers" it seemed like it might be a fast, easy and
viable alternative.
