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.
Where are the docs? Hwo does it work?
The docs are in the interfaces wiki: http://www.zope.org/Members/michel/Interfaces/ObserverAndNotification (Note that this actually predates the fishbowl process -- this has been in Zope for a loooong time).
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.
Looked... any further progress?
Nope, the PTK work I have been able to do lately is all stabilization. I am working an a new "PTK Fishbowl" site, where such proposals can be tracked more cleanly.
