Yes.

I don't think that recurrency is supposed to work atm. AFAIK the old 
iCalSaxDriver could not properly parse it.
Now I don't know the current situation wrt recurrencies, since we 
recently moved to the new versitSaxDriver (written by Max Berger and 
ZNeK).

Yes. iCal recurrencies do not match OGo recurrencies. In OGo 
recurrencies are individual (but connected) database items after 
creation while in iCalendar recurrencies are represented by a so called 
"recurrence rule" which is "calculated".

So when ZideStore receives an iCal PUT of a recurrence, it is supposed 
to create an OGo recurrence sequence. On the next query OGo will return 
all items as individual events (because its close to impossible to 
reconstruct a rrule from the events).
Note: I'm not sure whether this already works properly, I guess not.

Well, it is implemented, but it needs to get fixed for Evo 2.x 
requirements. We'll do this.

Actually contact modification AFAIK only works with PROPPATCH (and not 
with vCard PUT!) in current ZideStore.
