I thought this is what people are already doing when they use the 
Hibernate ORM on jbosgi (since Hibernate ORM is a component).  I think 
the Hibernate team is already contributing quite a bit and I see no 
reason to accuse (insulting) them of not being good citizens of the world.

For standalone use though, what is the model for getting the jbosgi 
framework as a single (maven artifact) component?  I'm asking this for 
my own information (not related to Hibernate native OSGi container 
support which I think is what Brett is talking about).  I have heard 
talk about *embedded* (framework/platform) support in the past but not 
sure if we have anything to show yet.
