BusySync - 2.0

BusySync allows multiple users to share and edit iCal calendars on a local area network or over the internet without the need for a dedicated server.

BusySync is a Mac OS X System Preference Pane that runs in the background and adds calendar sharing capabilities to iCal. Leveraging Apple Sync Services and Bonjour, calendar events created by one user are instantly published and synchronized with other iCal users on the network. Users can share and edit calendars, make changes on each others calendars, and everything is automatically synchronized between each user, on each Mac.

• Bonjour networking - BusySync automatically synchronizes calendars with others on your local area network. No dedicated servers or complicated network settings to configure. It just works.
• Wide area networking - Sync calendars between your home and office Mac over the internet. Or take your laptop on the road and automatically switch between Bonjour and internet syncing.
• Multi-user editing - BusySync allows multiple users to share and edit calendars with full read/write access. Changes made by one user are instantly synchronized with all others on the network.
• Security - Calendars can be password protected to provide different groups of users with different access privileges including read/write, read-only, or no access.
• Offline access - Changes made to a shared calendar while disconnected from your home or office network are automatically synchronized when you return.
