Isn't that a contradiction? What good is an rrule if you can't display 
it? Of course I believe you that you can parse the iCalendar structure 
of the rrule, but what good is the data if the user can't view/edit it?

Unless I'm missing something, not reflecting the rrule in the GUI is 
exactly the same like not supporting it. And reflecting _all_ the 
specified rrules in iCalendar should be quite difficult (if not 
impossible if you still want to have good usability ;-).

My impression is that a lot of clients use a similiar subset of the 
specified rrules and that this subset works pretty well. But it might 
be wrong.

Also most of the newer clients are specifically build around iCalendar 
which obviously improves on that too.
(eg comparing interoperability between Sunbird and Kontact should be 
done, but isn't particulary interesting since both use some derivate of 
iCalendar. One would need to compare interoperability between eg 
Outlook and Sunbird or Notes and Kontact).
