The code could be adapted to write iCal information, but AFAIKT Google
does not allow WEBDAV write operations. At the moment i am using
Google Calendar as my main appointment calendar, and org mode for
scheduling tasks etc.

If you want to sync to an iCal WEBDAV source an example of how its
done can be seen here:
http://www.emacswiki.org/cgi-bin/wiki/ElDav

You can only write to a Google Calendar with by using its gData
ATOM/RSS based protocol. There are some free client libraries, but i
have not looked into it in much detail.
