Actually there is no reason that a fixed IP is ever used. You actually
don't even need a fixed hostname (at least above the per-connection
level, you do it for convenience).

Simple. Signal strength from at least three access points will pinpoint

To fix this, change your MAC address (or whatever WiFi uses for that),

You can use GPS as naming service (name collisions are then equivalent to
