Delegate, Designate, Proxy, Sharing Role, Whatever

The simplest things to describe are almost invariably the ones that go by dozens of different names as vendors either try to give you the impression they're differentiated or try to make it easier to comprehend their features.

So to try to make some sense of the way "Delegate" or "Proxy" (our two favorite ways of describing selectively giving view or edit rights on your calendar to someone else) among the calendars we most often see we put together this table.

The wild card in all of this is Oracle Calendar which has a lot of functionality in its own domain which (by definition) does not transfer exactly to less rich domains (like Microsoft Exchange).
