Nice.   I'll have to remember that one.

Actually, they don't do everything that (open source) software encryption does.
They don't let you (or you an agent of your choice) audit the
encryption algorithms/implementation to verify that everything is
being done to spec.
Now I admit that I've suggested in another thread that for MOST people
ultimate security
isn't required, but that doesn't meant that it isn't sometimes a good
idea.   In this case, it
is more like not trusting firmware programmers not to screw things up
inadvertently rather
then being concerned about backdoors inserted by 3 letter agencies.
