If you're iCal-based for your scheduling needs and you want to share calendars with family or colleagues, you're probably already hip to BusySync and the delights of iCal syncing Mac-to-Mac without a .Mac account. Now the BusySync team has announced a key feature for 2.0, shipping in February: Google Calendar synchronization. You should be able to share calendars across the internet with other Google Calendar users, and if they have BusySync on their machines the Gcal data will slide neatly into iCal for them.
BusySync 2.0 will ship for $24.95 per computer, a $5 price increase -- if you buy a BusySync 1.5 license today for $19.95, you can upgrade for free to the new version. There's also a public beta on the way if you want to check it out.
