Looks spiffy. I like the approach of keeping even the database as part of the application. I think it makes projects a lot more like appliances, which can really be more plug-and-play. I see a lot of databases moving towards the application layer (CouchDB, Firebase), but it's interesting to see applications going the other way.

Lastly, here's to the hope of an exploit named "Pwnzu" never getting released! It's simply too good of a name.
