Thanks for that, Ed.

At this point, we are having our deployment keys applied to XOs in the
factory and field in addition to the standard OLPC keys. Our XOs are
not developer locked, but I'm creating the option to lock them later
on should the situation ask for it. It likely will be quite a while
before we seriously consider it.
