True.

Okay. Sounds reasonable. Multi-Indexing can be done by hard
links :-)

It's definitely cleaner than my hack, that's for sure. And
potentially much more functional. If needed, we can always
write different backend modules, once the abstraction layer
is in proper shape.

Do you also plan to write encapsulated wrappers to
manipulate the db? The default would call out to the 'add
user script'. Hmmm. We also need to plug in the new LDAP
stuff in there. Much design space to explore :-)
