yeah, but that would simply be merging the results from the queries
across the multiple databases. no transaction involved.

we could consider putting user profile information back into a
separate database, one that would not be partitioned like the home
directory database. this would allow us to query one data source for
administrative user management and for profile management, but the
really big data that presumably requires partitioning would be stored
elsewhere. this is precisely how we did things at cpth.

(the irony of course is that we originally had that architecture, but
the user store was an rdbms and the home directory store was
jackrabbit, and it made a lot of sense to unify the two.)
