Just as AT&T has begun offering subsidized netbooks with 3G data plans, the company took some aggressive steps today to manage network traffic and make its service a lot less attractive. Specifically, the carrier updated its wireless terms of service to forbid P2P movie downloads, web bradcasting and "customer initiated redirection of television or other video or audio signals via any technology from a fixed location to a mobile device."
In other words, it effectively prohibits everything from Slingbox and Qik to Skype and Hulu while using AT&T's mobile data services. It remains to be seen how strict they'll actually be enforcing these new rules, but it goes to show how adamant they are about protecting their business by picking exactly what activities you may and may not do with your Internet connection.
