Hi, I have a macbook and an iMac, and I'd like to sync them together (iCal, addressbook, bookmarks etc). I don't want to buy the .mac membership (I used the trial version, find it not worth the money, but syncing was kind of neat). Is there anyway to sync my two macbook and my imac together without .mac? I have a firewire, and bluetooth is readily available. Thank you.
