If one is ready to give these ones up, I think we can have pretty easily something running without speed loss (I'd even bet on a speed gain). All it'd take would be the MPL book example cooked with the MSM sauce.

That'd be great. Let me know how I can help.

First of all, what would really help would be if you (and any other interested) could list me the main UML features you use so that we can define what the mini backend must provide in addition to what the book example does.
