Lee Brimlow has released a video detailing how to get started with remoting with AMFPHP. AMFPHP is a free open-source PHP implementation of the Action Message Format.
I have used AMFPHP explicitly on my most recent project, cellpaint.com. AMFPHP is a great way of sending large pieces of data, like byte arrays, to a server and back.
