Thanks lorelei!

For those who previously asked about shared calendars, the answer is currently no. However, a simple change from GetOwnCalendarsFeed() to GetAllCalendarsFeed() in the file erminig-ng will allow you to sync shared calendars as well.

As mentioned in my previous post, erminig-ng does not preserve the read-only status of calendars, so I'd expect breakage if you modify shared read-only calendars on your device.

I'm hoping to find time in the next week to look at preserving the read-only flag and colors from the google calendars. I'll submit a patch here if I do!
