But what if some of your customers already run IB/FB? And what if at
present they don't, but later install IB/FB apps that expect a
decently working server?

I'm definitely not an Interbase expert, but my suggestion would be: if
your application's data is so sensitive that not even SYSDBA and/or
the superuser of the machine it runs on should be allowed to see it,
have your app encrypt it before storing it in the DB.
