BusySync shares iCal calendars

BusySync is designed to allow users on a local network to share and edit calendars. It works without requiring a dedicated server (unlike iCal’s multi-user capabilities in Leopard, as the developers indicate). Shared calendars can be edited by other users on the same local network. All information remains synchronized for each user.

Features include support for Apple’s zero-configuration (called “Bonjour”); multi-user editing capabilities; access restrictions, including read / write, read-only, or access denial; as well as access without the need for an online connection. The product is localized in English, German, French, and Japanese.

BusySync requires Mac OS X 10.4 or later, including Leopard, and it is a Universal binary that runs natively on Intel and PowerPC computers.
