[Andreas] I would be intressting to see how you could utilize aspect-orientated programming to get around having to derive all of objects that should be able to persist from a given class. Adding the layer of omnipresense to a class is sweet music to my *not-been-getting-my-hands-dirty-working-on-production -code-since-i'm-still-a-student* ears. >*** It might.
