Hadn't considered this. Does the sharing panel enables remote access
for all user accounts? That would not be very intuitive....

g-i-s and g-c-c could save the password strength when the password is
set. But if you set your original password some other way, then the
only way would be to force the user to enter his current password.
Which has to be done anyway to set the new one, so we probably just
assume the current password is not strong enough?

I think that's probably what we want.
