The solution is cooperative processing systems, where both the host and the terminal cooperate to perform some task. Unfortunately, there is precious little software infrastructure to support such a development. Terminal programs on PC's are still for the most part acting as dumb terminals, with the notable exception of file transfer protocols such as zmodem. What would the two systems be cooperating about? I'm not sure to what you are pointing. Although this topic is not directly related to cryptology, it is certainly appropriate for discussion on this list. It is the cypherpunk goal for widespread use of crypto by the masses, and the exact nature of the infrastructure necessary for that task should be debated, then implemented, then deployed. I of course map these suggestions into Joule (the language I'm developing). Does that resemble what you're thinking of? dean
