In the worst case it's possible for plugin to copy component from database to
file and load it normally. Unability to load Delphi routine directly from
database should not be showstopper to store external routines/classes/etc. in
a database.

Certainly, we must have well defined user's rights related with defining
external routines. Without it we can easily return to problems, when any user
with valid FB login may execute any code in context of firebird server. For
example, if any user would be able to create database (becoming it's owner)
like now, being DBO should not be enough to define external routines in that
database. With Java we may be can use J2SE to limit what class does, but with
Delphi - hackers will say 'Thanks, guys' :).
