Westausatc,
Great post.
I would like to point out that nabbing someone randomly at customs falls into the 'small fry' category. If you are a target of interest then they can already access everything you have on your computer as long as you are online, wherever you are... yes, despite your best efforts at protection. Mind you, if you are a NSW public prosecutor and have 59 prominent people as character references you may not have to worry too much.
