SQL would be just terrible for FS semantics to standardize on, and 
hopefully we will be able to deploy a semi-structured querying language 
alternative (www.namesys.com/whitepaper.html) before they ship.  I was 
sort of expecting that they would be late, as they don't yet have a good 
technical foundation in their FS storage layer for adding database 
functionality, and we surely know that's a lot of work to create;-).
