This code publishes an iCal file that can be subscribed to in Google Calendar. They change the way they interpret iCal data occasionally, so this may break, I'll try to keep it up to date.

There is some crazy string replace stuff going on there, I haven't yet convinced vObject to format things properly.

Feedback welcome.

*Note: this works for my existing feeds, but if I add a new feed to GCal, the timezones are incorrect, I'm working on that.

Or use django-cal for iCalendar files generation a la django.contrib.syndication.
