Well, I think that taking a stepwise approach would be good enough for the time being, just to see how much e.g. Jackrabbit would benefit from Neo4j. So, IMHO, the SPI implementation would be a good start without straingin teh resources available for this too much. As more peers are getting interested, we can always expand on that, but the Jackrabbit SPI impl would give a least working system.
