BusySync 1.0 released
BusyMac today released a new application, BusySync 1.0, its new calendar sharing utility for iCal. BusySync is designed to allow multiple users to share calendars on a local area network, without the need for a dedicated iCal server. Calendars can be edited from any user on the network, and the developer advertises that any changes will be instantly published and synchronized with all users sharing the calendar in question. BusySync is available directly from BusyMac's site for $20.
The utility ships as a System Preference Pane that runs in the background, acting like a plug-in for Apple's iCal program. Calendars created by one user synchronize with others through Apple Sync Services and Bonjour. Password protection is available, providing different access privileges to users, which dictate who can view or edit a calendar. Offline access is also available, so that changes can be made while the user is away from the network, and changes are synced upon their return.
Mac OS X 10.5 Leopard Server will include a dedicated iCal service, but BusyMac notes that the feature will not be useful in home or small office environments where a dedicated server -- a computer that has no other purpose but to provide a particular service or services to a network -- is not a cost effective investment.
