Using a powerful high-frequency modulated infrared source (eg, a bank of LEDs) located on a highly visible place, it couldbe possible to facilitate local community broadcasts, effectively sidestepping all FCC regulations.
The advantage is absolutely no laws regulating using of infrared beams for data transmissions. The disadvantages are the need to use special equipment for receiving (though possibly very cheap), the line-of-sight requirement, and possibly couple more. Using of infrared beams for establishing of data lines is fairly common (see eg. project Ronja, http://ronja.jikos.cz/ ). It involves bidirectional directional data transfers. However, if we use omnidirectional transceivers and directional receivers and use only unidirectional connection, we can use the same principle for broadcast as well. (The disadvantage is that we need to use comparatively huge power for driving the broadcasting LED banks. The advantage is that we don't have nearby sensitive receiver circuits that would be jammed.) Maybe it's unusable. Maybe it isn't, and somebody will find some use for this idea.
