Have you ever thought of using your experience with IDEs for PL/SQL to develop an Eclipse plug-in for PL/SQL development.... I think you could charge at least as much for this plug in as you do for the entire PL/SQL Developer IDE... As far as I can tell, there is really no good PL/SQL plug-in for Eclipse... There are good SQL plug-ins, but nothing that provides the great IDE you have in PL/SQL Developer.

We have had a few more requests for this, so we'll definitely look into this in the near future.

Has the near Future come any nearer by now?

The future always comes nearer, and this is still on the to-do list. The problem is that there have not been many Eclipse requests so far.
