I'm trying out Google Calendar and the interface is nice. It looks like it could be a good tool to help me coordinate my busy life with my wife's busy life. Unfortunately, my company uses Outlook for calendar events and it doesn't seem possible to establish a live link to that data. You can export your Outlook Calendar and import it to Google, but this would probably only be something I would do weekly so the calendar would essentially be out of date...not a real good solution.
It would be nice if there was a way to maintain a live data version of my work Outlook calendar (which I use to track all personal appointments as well) so that people not in my company could see my calendar and stay on the same page with my schedule.
