At the moment on my O2 simplicity contract I can use VoIP, MSN, Skype and streaming audio/video without issues. I quite frequently journey up and down the M27 Motorway with Fusion Radio Chicago streaming.

This recent stink kick up could change all that. The service won't be dramatically affected if they sort out bandwidth issues! P2P I can agree with a block on, use a broadband line for this as it hoards so many connections and bandwidth.
