Your dream is not too far away from reality. Devices like Mozilla's Things Gateway (https://iot.mozilla.org/gateway/) represent some of the most ideal fog nodes as they are inexpensive and fairly powerful. Not too long ago there was even a research project called Paradrop (https://paradrop.org/) which made a fog node out of a consumer-grade router. My company is working on modeling software right now for Fog deployments and hope to use the knowledge we gain to build our own fog computing solution. Our first application will likely be either a fog-based filesystem (already done by researchers within Princeton's Edge Lab) or a Fog-based backup / NAS solution. It'll be a while before we get to this stage, but it's emerging from the mist so to speak.

Also for anyone interested in how the Cloud, Edge, and Fog computing models differ, I wrote a blog post about this topic (http://pratumlabs.com/blog/2018/01/what-is-fog-computing/) a few weeks ago.
