Bernie, I think that the idea is the same, but we're just putting aside the
USB stick, and the logitics involved in provide and recover them, or
checking that the students or teachers have one and know how to do the
procedure. Anyway, USB o Repo we will require them to do the same update, I
just think that the second method provide us a more effective method to
reach a lot ( for now 37) of very distanced schools with a few qualified
personal.

I had some feedback also, and some teachers doesn't want to do the update if
they don't do the task with technical staff or they don't have a USB sticks.
