Back in the day, there were users of Fido technology networks who were concerned with email privacy. They applied a technology called PGP to secure the contents of their messages.
Folks, We are talking about changing an existing system -- one with an installed base of perhaps 1B users, but it's fine if we instead use the much lower number of some "mere" hundreds of thousands of servers. For such situations, it is considered essential to find a way to obtain incremental utility, for incremental adoption. It is also considered essential to minimize the critical dependencies for adoption. It is considered particularly risky to have one strategic adoption decision depend upon another, especially when the second has a history of more than 10 years of failing to gain major adoption (or rather, use.) We could go into a long and painful discussion about the reasons these lessons are valid, but the reality is that they are not all that difficult to appreciate, if one looks at the process of obtaining global adoption in a voluntary environment. d/ --- Dave Crocker Brandenburg InternetWorking +1.408.246.8253 dcrocker a t ...
