I spent the last two days attending the CalConnect.org meetings that were at the UW. I was filling in for Lisa, who took ill at the last minute. This was a good excuse for me to get caught up with what's been going on with the CalDAV spec. The folks that were testing CalDAV interoperability have achieved quite a bit, which is very exciting. I'm not going to steal their thunder, so you'll have to wait until the public test results are posted at CalConnect.org. If you are interested in the calendaring space, you should keep an eye on what's happening with CalConnect (of which OSAF is a member).
