Yeah, I suspected that :-)

He is responsive in the sense that he likes to see the code live, and is 
happy to share his performance benchmarks, but doesn't have time for 
very much more. Which is what it is like for most of us, I guess... 

We have Alberto on the list too, I think, perhaps he knows a bit more 
about the potential of it?

Yeah, but that's the niche I see for it, beside hexastore as a memory 
model and Virtuoso for the large RDF store.
