Specifically addressing your suggestion, "Require-Bundle" only deals with
resolving the named bundle and has nothing to do with provisioning.  So the
target bundle in a Require-Bundle clause must already be installed and
resolved in the OSGi container.  The closest thing to a standardization of
an "Uber" bundle is in the Deployment Admin spec in OSGi R4.1 but there are
some limitations that make it unsuitable for the "features" functionality,
at least in its current form.

I hope that over time there will be a new spec or revision to Deployment
Admin that will fulfill the same functionality as "features" in ServiceMix,
but for now it is really a nice thin layer that works fairly well,
particularly when used with a maven repository.

Thanks,
Chris
