1. A system for providing respectively customizable interactive audio/video content to each of a plurality of computing devices during a networked communication session, the system comprising: non-transitory processor readable media; at least one processor operatively coupled to the non-transitory processor readable media, wherein the non-transitory processor readable media have instructions that, when executed by the at least one processor, causes the at least one processor to perform the following steps: define the networked communication session as a function of parameter information received from a first user computing device; provide first access to the networked communication session to the first user computing device; receive, from the first user computing device, information associated with at least one additional user computing device; provide respective access to the networked communication session to each of the at least one additional user computing device, wherein functionality afforded by the first access is different than functionality afforded by the second access; generate a composited interactive audio/video feed comprised of audio/video input received during the networked communication session from each of the first user computing device and each of the at least one additional user computing device, wherein each of the first user computing device and each of the at least one additional user computing device is configured via a gesture-based user interface; detect activity representing the first user computing device interacting via the gesture-based user interface; generate a visual simulation effect, substantially in real-time as the activity is detected; alter the composited interactive audio/video feed by overlaying the visual simulation effect; and transmit, to each of the at least one additional user computing device, the altered composited audio/video feed to represent the activity, wherein the gesture-based user interface enables a customized representation of the composited audio-video feed at a particular one of the at least one additional user computing device that is not represented at a particular other of the at least one additional user computing device.
