I agree. This has happened partly because of a historical accident; SMS was never expected to become important, so it was implemented almost as an afterthought on the sides of the call signaling protocols and networks, not as part of the call content. For a variety of good technical reasons, call signaling bits are more expensive to transmit over the air and process on the ground than bits that are part of a voice or IP data stream, and the rates for SMS partly reflect this. But most of the price differential between the bit prices in a SMS message and in a phone call is due simply to the carriers' ability to charge a lot and get away with it. In the early days of digital cellular, the carriers made voice almost into a commodity with bigger and bigger packages of minutes, bundled long distance dialing, friends-and-family plans, etc, so they needed some high-margin ways to make mone > Net neutrality should be concerned with unfavourable throttling of > competitors traffic (Skype vs 'ABC' VoIP on the 'ABC' network, for > example) or with undisclosed limitations to service (Comcast apparently > being the most notable example at present). I agree. A very large part of non-neutrality is discrimination on the basis of the meaning of the bits that users send. This can be thwarted with cryptography. Another part of non-neutrality is discrimination based on where the bits are going. This cannot be prevented with cryptography as the carrier has to see the IP destination address to do its job. This makes it a thornier problem.
