I meant configuration from a database, like ldap. :)

This would also work for LDAP, it could be a partition.  Will there be a
back end API to plug in LDAP or database queries?  Or were you thinking 100%
file based?

I'm wondering if we really even want to abstract LDAP or database queries
though, since to do it right we would need a back end API.  I guess it would
be enough for a person to be abble write a mod_ldap that could add entries
to the configuration structures in the new config scheme.  That would
require exposure of the data types, or again an API. :/
