Very cool idea. It would probably be 100x more useful if it was easy to sync with other address books, I think I agree with you there. Perhaps this should be a priority. And any help you can give would be most welcome.

I think the reason I didn't find starting a new address book from scratch to be a problem for my own "itch" is that the previous non-existence of a CLI address book had always prevented me from building up any decent amount of data in any other place!
