This is already possible, technically, though I understand the  
difference of your approach.

Not necessary, because we already search for the events' UIDs in all  
calendars.

This is an interesting idea. Do you have any numbers/ideas/experience  
how relieable the X-WR-CALNAME and X-FUNAMBOL-FOLDER attributes are?
The problem I have with that approach is, that those are calendar  
*labels*. They can be changed, and they are not necessarily unique.

This already works, because moving an event adds a "delete" and an  
"add" entry in the history storage.

> - Rename the calendar on Outlook/Kronolith, will update the other side
> calendar name

How does that work, i.e. how do you know the original calendar?

Already works.

Do you mean recurring events?
