These merged ics files can be made available through a webserver, so all users can then easily subscribe (read-only) to the ics/webcal feed for everybody else. This was, in our case, impossibe to do in a stable or easy way using CalDAV delegation...
iCalDAVMerge is based partly on merge-ics and requires iCalendar.
The scripts were built for an iCal Server environment. Certain paths in the scripts may need to be adapted if running Darwin Calendar Server.
