BusyMac has launched the first version of BusyCal, a new calendar application. The software shares calendars over LAN connections as well as the Internet, in either case bypassing the need for a central server. Edits can be made by multiple users, and once committed they are synced to other group members, as well as to iCal, MobileMe, Google Calendar and iPhones. More hardware and software should be compatible through Sync Services.
