Apple's solution to this problem is iCloud, which is how I lost my address book a few months ago. Took a half hour of wrestling with Time Machine to get it back. Years ago, I'd have said that it should work if you simply keep your ~/Application Support folders in sync with a general-purpose file-syncing app. But, as you've found, Apple has been making this more difficult and that may not work. Anyhow, you should look on macupdate.com or appbodega.com for either a general-purpose file-syncing app, or even better, an Address-Book syncing app that will work over your local network.
