[Zope-CMF] ICS support for CMF Calendar

I'm working on a ics(vcs) view for CMF Calendar as it's something I  
use quite a lot myself.

A couple of things:

* the vCal format isn't really suitable for a PageTemplate although  
it is possible. Are there any other options?

* I usually generate a unique hash using md5. CMFUid doesn't seem to  
support generating a hash for an object so it's probably not the  
right tool. Should I extend Event.py for the UID or just use a  
string? The UID in a vCal doesn't seem to have much relevance outside  
of a subscribed service, ie. you can have lots of events with  
essentially the same UID in calendar. At least neither Outlook nor  
iCal seem to mind and will continue to create new events.

* is there anywhere I can extract the timezone from apart from the  

* should events come with default alarms?

Comments, as always, welcome.
