I just had this brainstorm that open spectrum should be thought of like an open source license. So that, the government would issue an open spectrum license for anyone to use a specific technology (e.g. spread spectrum) on a specific set of frequencies (e.g. 2.4GHz). But what would be the "Free Software Guidelines" for open spectrum? What is essential and what isn't to have open spectrum. If you're interested in the intersection of open source and open spectrum, check out (and reply to please :-) my post on the Open Spectrum mailing list at OpenICT.net .
