Dan,

Sure, but SPARQL+SQL (SPASQL) != SPARQL . Of course, you have the case 
of Virtuoso extensions to SPARQL, but those are only specifically in 
play (or promoted by me) when the solution scenario at hand isn't 
addressable using SPARQL in its current form.

Portable SPARQL and SPARQL applications to real problems aren't always 
aligned re. DBMS exploitation esp. in the enterprise realm.
