I have plans to implement this. Exposing QGIS layers as SQlite virtual
tables. This would give a lot of query bang with low code change   It was
done in OGR and works really well, of course it sucks with performance if
you do something really complicated but otherwise it would give QGIS a good
edge - if you need more power then more to a better database. A basic
query-everything type system.  This is something that MapInfo had and is a
bit of pain to loose when coming to QGIS.

I hope to start work after 2.4 is out.
