OK, another update - with two devices on the same Horde account, when  
you edit the appointment on one device to remove the invitee, which  
fixes it for that device, that obviously initiates a re-sync.  
Re-syncing the appointment back through Horde AS to the other device  
then resets the second device's state to have the originator as an  
invitee again. So fixing it on one device breaks it on the other one,  
and vice versa.

Generating an invitee-free invitation on one of the iOS devices works  
fine for THAT device. No invitee is added. But when it syncs through  
Horde AS to Kronolith and back down to the other device, the organiser  
is added as an invitee, and the problem re-occurs.
