My belief is that the core purpose of ham radio is experimentation, so playing with modern protocols, modulation schemes and techniques is really important for it to remain relevant in the future. It can't forever exist as an HF/VHF AM/FM service forever. The future is AES/RSA, DSSS/CSS, internet access, and mobile mesh systems.

All that said, if we went to allowing it with a cleartext ID, how do you think the crypto scams would defeat that in a scalable way?
