A system, comprising: a) a portable smart device, PSD, which includes (i) a processing system, which includes a processor, (ii) at least one wireless communication interface, implemented at least partially in hardware, through which the processing system can communicate externally, and (iii) computer-accessible tangible storage, including data and software instructions used by the processing system, (iv) a user interface, UI,, and (v) a geolocation system (570, 571) that tracks geolocations of the PSD; and b) a fan software application, FSA, which is saved in the storage and is executed by the processing system, that (i) transmits a sequence of the geolocations through a first of the wireless communication interfaces, directed to a first fan network management system, FNMS, (ii) based upon the transmitted geolocations, qualifies the PSD as attending a first event by the first FNMS, wherein the FSA is characterized in that it further (iii) receives a communication, from the first FNMS over one of the wireless communication systems, metadata that describes an item of digital content, (iv) receives through the UI a user communication that directs the FSA to obtain the item, (v) makes a determination by polling whether some second PSD, which has qualified with the first FNMS as attending the first event and has qualified to receive event networking services, ENSs, from the first FNMS at the first event, contains the item and is accessible directly by one of the wireless communication interfaces of the first PSD, and (vi) requests and obtains the item directly from such a second PSD if possible based on the determination, and otherwise requests and obtains the item from the first FNMS. a) a portable smart device, PSD, which includes (i) a processing system, which includes a processor, (ii) at least one wireless communication interface, implemented at least partially in hardware, through which the processing system can communicate externally, and (iii) computer-accessible tangible storage, including data and software instructions used by the processing system, (iv) a user interface, UI,, and (v) a geolocation system (570, 571) that tracks geolocations of the PSD; and (i) a processing system, which includes a processor, (ii) at least one wireless communication interface, implemented at least partially in hardware, through which the processing system can communicate externally, and (iii) computer-accessible tangible storage, including data and software instructions used by the processing system, (iv) a user interface, UI,, and (v) a geolocation system (570, 571) that tracks geolocations of the PSD; and b) a fan software application, FSA, which is saved in the storage and is executed by the processing system, that (i) transmits a sequence of the geolocations through a first of the wireless communication interfaces, directed to a first fan network management system, FNMS, (ii) based upon the transmitted geolocations, qualifies the PSD as attending a first event by the first FNMS, wherein the FSA is characterized in that it further (iii) receives a communication, from the first FNMS over one of the wireless communication systems, metadata that describes an item of digital content, (iv) receives through the UI a user communication that directs the FSA to obtain the item, (v) makes a determination by polling whether some second PSD, which has qualified with the first FNMS as attending the first event and has qualified to receive event networking services, ENSs, from the first FNMS at the first event, contains the item and is accessible directly by one of the wireless communication interfaces of the first PSD, and (vi) requests and obtains the item directly from such a second PSD if possible based on the determination, and otherwise requests and obtains the item from the first FNMS.
