Jon Udell tries to hook up Outlook calendars and Google calendars - and demonstrates the issues that non-propeller heads are going to run into. The interesting thing is, the issues aren't really due to MS or Google actively playing walled garden games; both support iCal, for instance. It's just that neither one really concentrates on interop, so the steps just aren't that easy. The post may end up being highly valuable for me - I don't use Outlook, but "everyone" else at Cincom does.
