1. A system for seamless interoperability between multiple computing devices, the system comprising: a server computing device having a memory and a processor; and a plurality of computing devices coupled to the server computing device, wherein the plurality of computing devices is defined at the server computing device as a virtual network of nodes and each computing device includes a memory and a processor configured to execute an ensemble module for exchanging ensemble messages with the server computing device; the server computing device configured to: receive, from a first computing device not currently defined as a node in the virtual network, a request to join the virtual network, the request including authentication credentials and a virtual network identifier corresponding to the virtual network; validate the authentication credentials; define the first computing device as a node in the virtual network based upon the virtual network identifier; transmit, to the first computing device, the ensemble module for execution on the first computing device; and receive, from the first computing device, an ensemble message for transmission to one or more destination nodes in the virtual network, the ensemble message being generated by a first application on the first computing device that is coupled to the ensemble module on the first computing device via a first application-programming interface and the ensemble message containing application-specific instructions for the first application formatted to be interpretable by the ensemble module, the ensemble message being received by a second application at each of the destination nodes that is coupled to the ensemble module on the destination nodes via a second application-programming interface and the second application formatting the application-specific instructions for the first application into application-specific instructions for the second application, and wherein the ensemble message is agnostic to the first application and the second application.
