I’ve made some modifications to this snippet if anyone is interested.
1. Most notably I’ve changed the &email parameter to &calAddress. This allows the snippet to support private calendars. Using the modified snippet you simply grab the XML url of your calendar (which is found at the bottom of the calendar details tab in your Google calendar settings) and past it into the &calAddress parameter. Multiple addresses can be separated by commas.
2. I’ve also added a &cacheDuration parameter to allow users to easily change the default cache duration of simple pie. If you don’t want to wait 60 minutes for your calendar’s feed to be reread set this to something smaller. The time is in seconds so, &cacheDuration=`30` would make the cache only last for 30 seconds (great for testing... useless for deployment: try something more like &cacheDuration=`900`, which is 15minutes.)
