Somewhere in the late 90s, I worked on the IETF IP over TV broadcast. I mostly observed and tried to ask smart questions, but it was really fun to be a part of the group. I learned a lot about both the technical side of radio frequencies, how to contribute to a group when I only had one area of expertise (TCP/IP) of many required for success, and how to manage and be managed remotely by a decntralized group. To this day I use AM for pushing packets around the property. There's no doubt standard radio broadcasters are an awesome way to pick up where the usual networks fall down.
