Is FindMeOn::RoseDB a Rose::DB subclass? If so, it has a dbh() method that
takes an argument:
http://search.cpan.org/dist/Rose-DB/lib/Rose/DB.pm#dbh
No need to be evil and reach into its hash :)

If the share_db parameter to the Manager call is true (the default), then
whatever Rose::DB-derived object the Manager used to do the query is
inserted into every Rose::DB::Object-derived object returned. If you do not
supply a Rose::DB-derived object to the Manager (using the "db" parameter)
then one will be created by calling the init_db() method of the
object_class. (The docs call this an object method, but it's called as a
class method in this case. The docs are updated in SVN.)

"Kill"? Why not just set share_db => 0 in your Manager call to keep any of
the returned RDBO-derived objects from having a db at all?

You should never know what those keys are anyway! :) (Also, column values
are stored in a few places, not just under the "expected" unadorned names.)
