Calendair(a combination of Calendar and AIR) brings together an online/offline calendar client, which will hopefully be using Google's Gcal API to work and store information both on the user's computer, and online, to allow for dual functionality when offline or online. At the moment, there is no current working dev, alpha, or beta for Calendair, as the creator is taking some time to learn the google Feed syntax, along with other various things involving google calendars.
