I'm looking for a way to keep my calendars and Address Book in sync. Can anyone recommend a way? I want to keep all the data as it is, though I don't want to use MobileMe.
http://fruux.com/ is the free MobileMe alternative for exactly that kind of setup.
And of course you could sync to the same Google address book and calendar, though when I tried that, there was always some information not sync'ed really well. But that was maybe just me. If you are interested, there are lots of how-to's out there, one being here: klick
Hope I could help.
I've been using BusySync from http://www.busymac.com, it costs about US$39 per Mac. Syncs Macs on a LAN and w/ Google Calendar
