1. A method for locating and displaying information about a user of a proximately located computing device, the method comprising: sampling a wireless communications signal to obtain one or more wireless data packets; retrieving a media access control (MAC) address from the wireless data packets that uniquely identifies a proximately located computing device that transmitted one or more of the wireless data packets; querying a server computer with the MAC address to obtain an internet protocol (IP) address assigned to the proximately located computing device; querying a server computer with the IP address assigned to the proximately located computing device to obtain information regarding a user of the proximately located computing device; receiving signal-to-noise ratio data for the one or more wireless data packets transmitted by the proximately located computing device; and computing a relative distance to the proximately located computing device based on the signal-to-noise ratio data.
