I'd like this too.  How do you propose to get this to work?  I've been working on several
ideas that end up requiring major modifications to geronimo that I haven't been able to get
to work.  Any ideas you might have would be great to see.

What I'd actually like to see is that, instead of arbitrarily importing any particular set
of classes, we run bnd on the application classes to determine the Import-Packages needed.

if they have problems with classloading and they are not willing to write deployment descriptors.
