This is awesome! I can think of a lot of good calendar applications. Hopefully I will get the time to start working on some of them.
Google Calendar allows client applications to view and update calendar events in the form of Google data API (“GData”) feeds. Your client application can use the Google Calendar data API to create new events, edit or delete existing events, and query for events that match particular criteria.
There are many possible uses for the Calendar data API. For example, you can create a web front end for your group’s calendar that uses Google Calendar as a back end. Or you can generate a public calendar for Google Calendar to display, based on your organization’s event database. Or you can search relevant calendars to display a list of upcoming events on those calendars.
Here is a way to insert your google calendar into googlepages.
I removed the link because the it does not show you how to insert a google calendar into googlepages. It was a link to the unofficial Google Calendar widget for the iGoogle homepage.
