The thing I find interesting is that this prohibition against any Jew ever pronouncing the Name is a product of rabbinic Judaism, which again started with the Pharisees, who were basically the only real organized group of Jews left after the Roman Wars and the destruction of Jerusalem. I often wonder what would have been the ramifications on modern Judaism if some of the other groups such as the Sadduccees and Essenes had survived that time (neither of those groups apparently bought into the Pharisees use of an "oral law" which eventually became the Talmud etc).
Of course, the Karaite Jews don't subscribe to the oral law, either, but my understanding is that they are a very small group.
