Why didn't we think of that before, duh.  It will require changes in 
cosmo but they should be minimal.  So does this mean a RECURRENCE-IDs 
should be serialized in icalendar as a UTC date/time or should the 
timezone still be included if the master's start date has a timezone?  
So for example:

master event:
uid = abc
startDate = ;VALUE=DATE-TIME;TZID=America/Los_Angeles:20070511T090000

modification
uid = abc:1178666002

When the modification is serialized as icalendar should RECURENCE_ID be:
;VALUE=DATE-TIME;TZID=America/Los_Angeles:20070511T090000
or
;VALUE=DATE-TIME;20070511T160000Z
