Jim Wynia has posted some thoughts about a recent announcement of the development of a WebDAV library for PHP to his blog today:

However, over the past few years, WebDAV has started gaining traction as the underlying protocol for Subversion repositories over the web and in several other places. That makes this story about a new PHP library for working with WebDAV interesting.

He notes that he's moved a lot of his file storage to Amazon's s3 service and having this new PHP library would make it even easier for him to get at his content directly from his applications.
