We do even more, we take snapshots as the "Layerfile" runs - this basically lets you merge the memory dump semantics you mention with the interface of Docker.

Also, we monitor which files are read by any step in the process, and let you skip setup chunks that don't need to run (i.e., installing libraries) without needing to micromanage what files you copy into the staging server.

Man that sounds cool. I don't have any use for something like that, but I would love to see it opensourced to play with it (which I assume you guys won't be doing anytime soon)
