You can't charge money for anything. 2. I think encryption falls in the lines of "codes and ciphers" which is explicitly forbidden. IIRC 2.4 Ghz is unregulated and you can do whatever you want to up there. "Ham" is restricted to frequencies designated by the FCC and I think only goes up to 1.2 Ghz or somewhere in there. If you're truly interested in trying to do some commercial wirelss stuff get your ham license and get hooked up with ham geeks. That way you'll learn everything you want to know about antennas, intrerference, power consumption, etc and also meet the right people who can help you out. A ham license will cost you a $6 testing fee. To study for the test I recommend reading through "Now You're Talking" and taking sample tests at www.hamtest.com. It took me about 3 weeks from start to test to get my license. -Brian
