Here's what I'm thinking: Small two axis servo gimbals that holds this device's antenna and your PC's WiFi device/antenna. Write a program to find the sweet spot, lock onto it, and follow it if it grows weak. Imagine devices like wireless IP camera's, TV's and game consoles, etc actively finding the best possible signal in a narrow sphere. Basically smart antennas! In places like coffee shops with constantly moving barriers, this would be awesome to maintain best connection strength.
