Not really. You need to keep your metadata repository in sync, so you 
need to intercept PUT, DELETE & MKCOL, acting accordingly on the JDBC 
store, so you would need a bit more than just proxying.

Not really. You need to keep trace of lock tokens, but it shouldn't be 
that hard.

Not at all, infact it was something I wanted to investigate sooner or
