Don't forget thin clients or web clients which may have little or no cache. 
I know several groups working on web-based solutions and they nearly always 
use the time-range reporting capability of CalDAV to retrieve just the 
events they need for display purposes. Our current strategy does deal with 
that reasonably efficiently in that time-range queries are handled via an 
sqlite DB for each calendar.
