Yes we need it for CPS which currently works with 2.7 (no customer is 
ready to move to 2.8 yet).

Yes events are the way to go. For 2.7 we have our (CPS) event system, 
and Julien has experimented with patching Transaction.py's commit and 
abort to send appropriate events. Then the rest is just a matter of 
subscribing and reacting to them.

I totally agree that if 2.8 could use standardized events from Zope 3 
that would be awesome.
