sockets webservices

I'm at BADCamp, which is awesome, and since we at AllPlayers.com (http://www.allplayers.com) are heavily invested in webservices and being a big proponent of using them for a variety of reasons; I asked crell, how I could help out. It was indicated that if I could start a discussion on how to perform socket level communications in php that would be a small help.

The second part of this being after a write-up on php socket communictions, would be to see if there are is any code in the opensource world that could be leveraged to assist in this manner.
