CalDAV server for PHP

It's been a long time coming, but I finally have some working CalDAV code. The server has been tested with iCal 3.0 and 4.0 (Leopard and Snow leopard), Sunbird 1.0 pre-release and Evolution.

My main goal is to create a general-purpose CalDAV library, rather than a consumer-ready server app. I'm hoping people will be able to use this library to enable CalDAV functionality in their existing applications.

If you're interested in hacking around or testing, you'll have to grab a copy from subversion. Full installation instructions are available. Because of the alpha-stability nature of the code data-loss can occur, so beware!
