Empire-db

I've been looking at empire-db, which appears to be a really interesting alternative approach to Java persistence - without the need for XML config, annotation config, yet more funny query languages, etc. It'll take a while to see how well it really works in practise, but it's definitely worth a look if it can cut down on all the pointless plumbing and/or SQL strings in code.

The main problem I can see so far with the approach is that it seems almost intended to encourage people not to separate out domain objects from the persistence layer, which isn't too good, but maybe I haven't fully understood what's going on yet...
