Media content selection and presentation control

A computing system, comprising:

• an electronic device configured to:
• receive a content polling message from a participant mobile device within a participation region of a wireless network;
• retrieve an attribute for the participant mobile device based upon the received content polling message, the attribute associated with a media content item stored at the participant mobile device or previously accessed via the participant mobile device;
• output an indication of the attribute;
• obtain a wireless signal strength measured at a wireless access point of a plurality of mobile devices;
• determine whether each wireless signal strength is greater than a threshold wireless signal strength;
• identify a first mobile device of the plurality of mobile devices as a non-participant mobile device responsive to determining that the wireless signal strength of the first mobile device is not greater than the threshold wireless signal strength;
• and
• identify a second mobile device of the plurality of mobile devices as the participant mobile device responsive to determining that the wireless signal strength of the second mobile device is greater than the threshold wireless signal strength.

An apparatus, comprising:

• means for retrieving an attribute for a participant mobile device within a participation region of a wireless network based upon a content polling message received from the participant mobile device, the attribute associated with a media content item stored at the participant mobile device or previously accessed via the participant mobile device;
• means for outputting an indication of the attribute;
• means for obtaining a wireless signal strength measured at a wireless access point of a plurality of mobile devices;
• means for determining whether each wireless signal strength is greater than a threshold wireless signal strength;
• means for identifying a first mobile device of the plurality of mobile devices as a non-participant mobile device responsive to determining that the wireless signal strength of the first mobile device is not greater than the threshold wireless signal strength;
• and
• means for identifying a second mobile device of the plurality of mobile devices as the participant mobile device responsive to determining that the wireless signal strength of the second mobile device is greater than the threshold wireless signal strength.
