The very simple point is that having some >basic scrambling of the signal is better than not at all! This is not necessarily true. Simple inversion helps me against my neighbor with a cordless phone (unless it's another Motorola). It doesn't help me against anyone wanting to eavesdrop for real. As long as I know how good (bad) it is, it helps, I suppose. If I ever let myself believe it's really secure, I'll be seduced into behaving with it as if I had privacy -- and would therefore reveal more than I should. In that case, "some basic scrambling" is far worse than having no scrambling at all. The best case would be the old ham radio sets with speakers and microphones -- no headphones, no phone handsets -- with the large antenna outside the window -- reminding you constantly that your words are being broadcast. -- -- <<Disclaimer: All opinions expressed are my own, of course.>> -- Carl Ellison cme@sw.stratus.com -- Stratus Computer Inc.
