Nicolas, yes, after looking into the details involved, I think an "official" superbundle with the core Neo4j components bundled and exported woudl be the best way forward. Also, it would expose less granular bundles into an OSGi environment.
Other IndexProviders etc could be then inserted as fragments into that bundle. It would be absolutely fantastic if you could work on that, maybe using the neo4j-osgi-examples as the demo project? We could then have a packaging project there or in a "neo4j-osgi" component that does the actual production of the superbundle. WDYT?
