1. A computer-implemented method for sending a message on a network, comprising: determining a source of a set of data elements; transforming said set of data elements, based in part on a set of rules, from a first representation of said set of data elements to a second representation of said set of data elements; monitoring said second representation using said set of rules, for an event that triggers an event notification message to be transmitted in real time; prior to transmitting said event notification message to a first designated wireless device, ascertaining if said first designated wireless device, to which said event notification message is to be transmitted, is present on said network based on information received via said network; if said first designated wireless device is ascertained to be present on said network based on said information received via said network, transmitting said event notification message to said first designated wireless device; and if said first designated wireless device is ascertained to be not present on said network based on said information received via said network, transmitting said event notification message to said second designated wireless device instead of said first designated wireless device, wherein said set of data elements pertain to information other than presence of said first designated device or said second designated device.
