Any kind :) I think that for what I have in mind though, some variant  
on your (1) is best (or simplest).

Has libb been updated recently? If not, you can give up on it. Andrea  
was sitting next to me when he wrote it, in fact I was the guinea big  
as it was meant to be used as the storage backend for Joost's video  
annotation tool (Joost used RDF rather heavily, if often  
unpleasantly). Andrea's a good coder so his prototype worked fairly  
well, but it was just a prototype. I don't know if he hacked on it a  
lot more, and what its status is now that Joost has been moribund for  
over a year. If it doesn't look updated, and Andrea isn't being  
responsive, I think you can write it off.

Also, I don't think it was designed to power large RDF stores. The  
original idea at least was to be fast for small, largely local (or  
highly partitioned) stores.
