I know I looked at this (probably at least 9 months back) and decided
against it for some reason which of course I really can't remember now.

I may look at using this with my reimplementation I'm about to do - the
db has changed, so a load of stuff needs to change anyhow.  The biggest
problem appears to be creating an ical file (other than really really
basic - ie no repeating events etc) which more than one client can read
and get the same set of times out of.

It looks to me as though the rules of thumb are:-
      * No timezones - do everything as UTC (Z timespecs)
      * Ideally no repeats.  If you have them then the end date should
        be set to 23:59:59 on the last date (no idea what happens if you
        are in a timezone where that pushes you into the wrong day)
      * Really really try to avoid repeat exceptions.  Nothing does them
        the same way.

I'll actually codify these properly when I dive back into this :-/

	Nigel.
