This has been a pipe dream for a while. The thought was that we could
just run Peter Kriens' bindex tool over a Maven repo to generate the OBR
repo.xml file and we'd be done...still working on it, though. We have
been trying to collaborate with the Maven guys on getting Maven to
generate bundles, but it is slow going since everyone it busy.

now I'm fully committed ;)
Think of the possibilities of Maven as a runtime repository as well as a 
develop time repository.   Chris mentioned OBR, but Maven repos filled 
with bundles would also be an enabler for maven aware (Initial 
Provisioning Service) Management Agents!
