If your encryption suite synchronizes passwords with login passwords, which
is true of most; and if you effectively enforce a policy of lock-on-sleep;
then I'm not sure how much real difference there is.

It's the not-locked-on-sleep case that will burn you.  If you can use GPO or
similar to *force* it, you're probably OK.  The problem starts with laptops
that are under the user's administrative control, not your centralized IT's
control. Then the clever-sheep user has the opportunity to disable
lock-on-sleep without realizing the full security ramifications...

(Go ahead - admit it. You have users that would do that if they could)
