Anyone know of a way to get the same general sync functionality of .Mac without paying $77 (Amazon) or $99 (Apple Store)? Basically, I'd like to synchronize my address book contacts, iCal calendars, and Safari bookmarks between two Macs automatically or semi-automatically through the use of an AppleScript or a UNIX shell script, or a cheaper freeware/shareware app. I have a domain name and hosting space, and a couple of gmail accounts, so I don't need the e-mail or web features... just the synchronization. Suggestions?
