[Ti] Protecting your Data [was: TiBook 1GHz/SuperDrive US Mac OS ROM file?]

[Robert Nicholson]

I still don't understand. You have it setup so that it will 
automatically mount the image via the password stored in the keychain. 
So what stops someone recreating that user on another machine by 
copying of the keychain and then logging in and having it automatically 
mount the image? One it mounts the image the data appears unencrypted 
right?
