Hi - I'm very intrigued by this idea, and I personally have access to a few towers, both privately owned as well as commercially, ranging up to 2000' in height.  I'd love to get on board in the Raleigh area with this, but the legality really concerns me, mainly in the aspect of transmitting encrypted signals, and in transmitting signals intended to be of a commercial nature.  For instance, the way I interpret the rules, one cannot utilize any form of secure TCP/IP protocol, and one could also not communicate with, say, any kind of website that may have advertising on it.  
Thoughts?
Thanks -

If you are that worried that something you or your users may do will violate Part97 then dont do it. Its your license.
