I'm sorry I "lost" this mail as I went on vacation.

There is an implementation of the Observable interface already in OFS:

  $SOFTWARE_HOME/lib/python/OFS/DefaultObservable.py.

The interfaces are documented in the Wiki:

 
http://www.zope.org/Members/michel/Projects/Interfaces/ObserverAndNotification

As soon as I squish some irritating 0.9.0 bugs, I intend to begin work
on an "event channel" for the portal, which provides for a more
decoupled
implementation of Observer.  My proposal for the channel is at:
