If you don't have a preference for iCal, then these suggestions are probably not of much benefit. But I'll mention them anyway, just in case others might find it useful.
The Leopard version of iCal
allows group sharing of calendars using CalDAV and other open protocols implemented on Apple's iCal Server and on a variety of opens source calendaring systems. I've never tried them myself, but they supposedly works well. Unfortunately, my office is also married to Exchange, Outlook, and Windows, and I doubt we'll ever switch. But I'm not particularly impressed with Outlook on Windows. :-(
But there are some tools available for syncing iCal with Outlook/Exchange too. Groupcal
is one of them. And I vaguely remember hearing rumors of Apple finally adding Exchange support to iCal in the upcoming Mac OS X 10.6 Snow Leopard, rumored to be released sometime next year.
For sharing iCal calendars within a small office without the use of a server (Outlook or others), there's also a highly-regarded application called BusySync
