Your approach shows the significance of the RDBMS/SQL
paradigm for any inference-based query answering system.
A query and inference server for RDF should basically 
provide at least as much expressivity/functionality as
a SQL-DB server (including negation-as-failure, as 
opposed to the views of the "conservatives" on this list).
