That's a great idea, I would add one minor modification.

Don't have the classes in derbyall.jar, just Class-path entries.

Class-Path: derbynet.jar derbytools.jar derbyclient.jar

Then it's (almost) the same functionality for almost zero overhead.

The name may want to change as well, something that indicates it's
really only for use as a command line tool. derbycmd.jar doesn't quite
seem right, maybe others have better ideas.
