Computational systems and methods for locating a mobile device

A system comprising:

• (i) an accepter module configured to accept a query from a radio-frequency identification object associated with at least one mobile device, the accepter module including at least:
• (A) a silent mode accepter module configured to accept a query regarding whether the at least one mobile device is in a silent mode;
• and
• (ii) a presenter module configured to present an indication of location of the at least one mobile device at least partially based on a query response from the radio-frequency identification object associated with the at least one mobile device, the presenter module being configured to present at least position data indicating a location of the at least one mobile device to a second mobile device, wherein both the second mobile device and the at least one mobile device are associated at least with a particular individual;
• and
• (iii) wherein at least one of the acceptor module or the presenter module is implemented at least in part with hardware.
