[AccessD] Bitlocker

Hello everyone.  I've been lurking for a bit but I'm still around.

John,

You're encrypting the entire drive?  I think you can also use bitlocker
to create a safe area (encrypted folders) for client and personal info
you don't want to "share".  Isn't bitlocker log on dependent?  Would
anyone else ever need to be on your machine logged in?  I don't think
they'd be able to open files if so.

My understanding is that the overhead is extremely low, so there is
little to no cost.  The benefit is that if the machine is stolen there
is no data loss.
