Bruce Eskowitz from Clear Channel let slip (or announced but no one noticed) that they have wired their venues for Wi-fi and would be rolling out services at the venues THIS SUMMER. Services include; Voting on encores, blogging, Text to screen, and other wi-fi enabled services. That turns clear channel venues into the ultimate user-content creation venue. It also raises a bunch of interesting issues like copyright, control of music licensing, critical bloggers, etc.
