Found (surfin blogs) Prevayler. Seems pretty cool, it's a framework to keep an app's entire dataset in RAM, with periodic backups and recovery via a transaction log. Think it would work pretty well, as long as you can satisfy the basic premise that you can afford enough ram to cache the entire app, ie small to medium datasets. Would like to hear the sys admins if I asked for a 20gig block of ram for my new app... but seriously, the last app I wrote, we had a day one data set of 12 gigs. RAM isn't *that* cheap.

I'd thought about doing something similar using AspectJ, still writing to a database, but controlling transactions and object state rollback / versioning using aj.
