Yes, the UI is bare-bones, and it does take some getting used to etc. We 
are going to a least make the basic UI a little clearer.

Yes, the whole idea here is about just that. Give developers a Web 
Services style interface to this functionality in addition to a native 
Virtuoso PL function.

This feature is all about the use case scenario you've just outlined.

We are DBMS Engine focused, and desperately would like the more UI 
focused in our community to simply bind to our backend services. In 
2009, across the Linked Data realm there should less of: nice looking 
UIs atop so-so backends or nice backends with so-so UIs .
