I ran across a great FAQ explaining the Open Spectrum concept. It reminded me about this important issue that very few people seem to be aware of.

The basic idea is that the FCC no longer needs to regulate and dole out portions of the RF spectrum. With new technologies like frequency hopping and software defined radio, we can now make our systems very resistant to interference, to the point of making it a non-issue. As it is, only a very small portion of the spectrum can be issued without a license (e.g., by any consumer devices). If the entire spectrum was opened, we would see an explosion of technological benefits. Cheap, high-speed Internet access virtually everywhere and all sorts of devices that could communicate with one another would likely be the result. It's hard to say just what innovations might come about.
