If you use multiple Macs and you need to keep a database synchronized between them, you may want to give Wooden Brain Concepts‘ DevonSync a try. This little utility synchronizes two DEVONthink databases on two Macs over the local network, the Internet, and with version 1.2 – released today! – also via .Mac! DEVONthink and the to-be-sync’ed database needs to be opened on both machines (even when using the .Mac mode), and DevonSync does only add items and does not delete obsolete items (for additional security).
