Actually, hams are in the "experimenting with radio" non-business. Communication is only one part, and, in fact, it's not actually described in Part 97 as a reason for ham radio (there are commercial licenses for those who need to "communicate"). It's equally valid to experiment with sending multichannel sound (can't send music, because it's specifically prohibited). I've fooled with doing immersive virtual reality using ham radio, and that requires multiple video and audio channels. The rules merely say use only the resources necessary (e.g. bandwidth and power), and for all the bickering about bandwidth, I'll bet relatively few hams ever turn the power knob down from "10", and certainly they don't adaptively adjust the power according to the link margin to keep a constant SNR. This is where software radios like the SDR1K and F5K are great. It actually makes it possible to experiment with new modulations, new applications, etc.. Just try and modify your conventional ham radio to carry multiple audio channels (well, ISB was available on some) or to experiment with adaptive power management (which is a standard feature in cellphones since day 1).
