This could be an excellent component and make JCal Pro go away for good and use Google Calendar to be the option of choice on most CMS systems including Joomla. However, there is a bug fixed here: http://www.jlleblanc.com/option,com_fireboard/Itemid,70/func,view/id,2039/catid,10/

Where event details don't show up.

Also, if you are not in GMT time, then your events will show up in that timezone confusing your clients to say the least. I don't know of a work-around for that yet.

It has a lot of promise and if it could be addressed I wouldn't mind donating some beer money to the developer. Until then it's neat, but not useful.
