That sounds like a solid idea - it'd be good to support the apps
adhering to the iCal specs (or both) as well in this area.  I'm not a
software developer by trade, though I could do my best to attempt a
patch.  However, if you have an idea in mind, feel free to lead the
charge.  Any patch I provide might be workable, but slow in coming and
likely ugly.  :-)

On a separate note, thanks for all the hard work thus far - in general
I've been very happy with Horde as my Exchange killer.

Respectfully,
