Looking for easy way to share iCal/Address between users

[qwikstreet]

I'm looking for away for my wife and I (multiple users) on one iBook to share our iCal and address book info without having to remeber to constantly publish, resubscribe, etc. I tried using that Now Up To Date and Contact app but found it clunky and not as friendly as the iCal and Address Book.

I've seen other apps like CalTalk and other hints of symbolic links to partitions, etc. Looking for some further and educated opinions.
