I don't think this is a huge huge issue here. if someone can get hold of your static /local file then person could try for months to drill into it and may be some day it will be a success. thats how .zip encryption was hacked. My password is still jk$3^hjRT so I hope I am safe. it takes me a while to type my passwd on BB but I am ok with my memory and BB thumb (hurt)
I wish BB OS will allow taking backup on to its memory card so that the backup file is not lying around on your old desktop. Less chance of falling the device in wrong hands.
Never be silent about the things that matter, but what about Democracy? That matters too
