Does IB have anyting simliar? And in an unrelated question - why would I NOT
want to go to IB? We are using FB now, but in one project we are looking to
go IB because of its ability to (7.5) have individual passwords per DB AND
be able to install multiple instances on a machine. Both of which are very
serious issues for us in one installation.

The installation the developers need sysdba access to all DBs but one - and
FB does not provide for this any way that I can see.
