motivation for routing a bit of 44.0.0.0/8

If a municipality is going to set up a city wide 802.11 network someone is going to have to keep an eye on all of the radio gear. HAMs have the skills ... but what is the motivation? Set up a separate SSID exclusively for HAM use. Use IPsec AH - cryptographically signed traffic keeps the unlicensed out without breaking the no payload encryption requirements. City gets help with the civil defense radio of the 21st century, HAMs get a new toy, and everyone is happy. Sure, there are security concerns, but the interface to the outside world is a proxy server HAMs can use while doing storm watch and such ... nobody gets in or out without a note from the FCC ... Or am I making this just a bit too simple?
