Mac-to-Mac sync, without .Mac

Hi, I'm looking for a tool that will help me sync multiple Macs against each other, without having to go through .Mac to do it. Items that should be synched include: - Address Book - iCal (calendar & tasks) - Keychain - Bookmarks - Files (can be limited to a specific folder, say, ~/Documents) It would be nice, but not required, if the user could specify Address Book groups / iCal calendars to sync. Obviously, one Mac should be designated as the client, and the others can be servers. I'd prefer the app to be written in Objective-C, but I don't much care about its UI, so long as it clearly offers these items as preferences. Thank you. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
