I don't really travel internationally, but I decided -- about ten years ago, when people first started talking about the way laptops are searched at borders -- that if I do feel the urge to travel internationally with my laptop, I'll dd if=/dev/zero of=/dev/sda on all my gadgets before I cross any national border. Of course you want to have VNC / ssh set up ahead of time so you can actually do stuff...
