Bluetooth memory stick


Sony has been showing a prototype of their bluetooth memorystick

If you don't know what bluetooth is it's a new standard for wireless stuff.  At its most basic it's supposed to allow you to use all your gadgets without needing to connect any wires to your computer.  For example your printer, scanner, zip drive etc.  This memorystick could potentially allow Sony digital cameras, digital video cameras and MP3 devices to connect to your computer without any wires.

What's not clear to me (I haven't looked into it) is how you prevent your next door neighbor from also using your printer, scanner, camera etc.
