Five already has had some work done in backporting the Zope 3 event 
system, so it'd be nice to be able to reuse this. I'd be willing to work 
together on this. I tried reasonably hard (there are at least some tests 
:) to get Zope to send the right Zope 3 style events on creation, copy 
and move.

If we backport the Zope 3 story, we'd need to worry about importing 
issues. If we backport Zope 3 events, what package will they live in? 
How will this relate to Five? What other packages does this draw in 
(zope.interface definitely)? Etc.

Five can make something send Zope 3 events right now by just another 
ZCML statement, though it drives a monkeypatch underneath..
