[Zope-dev] Event & Timer Service for Zope 2.8

I noticed there was a thread last month on an event service for Zope.  
Did that reach any conclusion?

 From what I can see the present products are:

- http://www.zope.org/Members/lstaffor/Xron - Zope 2.6 only, not being  
developed
- http://zope.org/Members/naumen/NauScheduler - shipped with one of the  
Zope CMS's works fine with 2.7
- http://dev.legco.biz/products/ZopeScheduler and  
http://dev.legco.biz/products/timerservice - works fine with 2.7 too
- http://cvs.zope.org/Products/Event/ - event service without a time  
service, not sure of development status
- http://mail.zope.org/pipermail/zope-cmf/2005-January/021747.html -  
Dieter's project to be based on Python's sched module
-  
http://api.nuxeo.org/CPS3/public/ 
CPSCore.EventServiceTool.EventServiceTool-class.html - CPS's event  
service
-  
http://cvs.sourceforge.net/viewcvs.py/*checkout*/mailmanager/ 
mailmanager/MailCheckThread.py?rev=1.15 - our custom scheduler for  
MailManager
- Zope X3's event service

It would be great to some consolidation of all of this into the core. I  
would also strongly favour a timer service along with the event  
service. I know that the argument has always been that operating  
systems provide time services but this is not very convenient for cross  
platform development and on some Windows platforms it's difficult.
