Well, it's like this. You use the TCPSocket to connect just like a web browser would. IP Address:Port (Port 80 is HTTP). Then, you must build an HTTP request to send to the web server. From there, you will get a response. You must then sift through the data you receive to pull out the XML markup that is in the response. Then, and only then, can you use this XML for the Pronto.

Philips did create some examples earlier on for the Beta Site. I'm not sure if these examples will be published for public consumption.
