Does anyone know what happened to it and how far its implementation got?
The preliminary implementaion, DefaultObservabale, landed as a mix-in class in Zope 2.2: $ZOPE_HOME/lib/python/OFS/DefaultObservable.py Mix it in to one of your Python base classes (be sure to get it's '__init__()' called!) and fire away. I am currenly working on the more ambitious notion of adding an event channel, which addresses some of the "MxN" problems which plague the classic Observer. See the Zope-PTK archives for August for the latest on that.
