Is there any PHP (+ xml?) equivalent (or similar) for this awesome .net library?

[Firefox Wins]

The newer version is called FeedSync and so far nothing found for php:
"The FeedSync Service is an ASP.NET and C# based sample application that provides the following..."

This is the best part:

• ...two-way sync with no concept of a "master" copy.
  

Google doesn't always help, so if you ever see anything in php which tackles this exact subject, please, update here.
Thanks again Zinga

• The PHPFeedSync project aims to be a complete PHP implementation of the FeedSync protocol

Only Atom is supported in the current release...  

Still looking to do this using PHP and (almost any) type of data format:
