Indeed, as a professor in fault tolerance, distributed system, and parallel programming I can confirm that almost nobody work on this. This work is quite fascinating and complete with operational hardware/software combo. Never seen that before! My university has done work like: "Cellular automata based S-boxes", nothing as ambitious as a post-Neumann paradigm.
Hopefully this work leads to a breakthrough on the ease of asynchronous software development. Academia never seriously looks at this due to the difficulty of coding for exotic parallel async architectures. Numerous people dedicated their lives to making coding easy. Centuries of human efforts and we now have Javascript, 1+ million people know how to code in that. Efficient coding using VHDL? Async FPGA stuff? 2D grid tiles? Not many.
Errmm time flies. More than a decade ago.
My theoretical and design work has been focused on concurrent modal languages (with nondeterminism as a basic side effect often), and I am going to be hopeful that I can find a useful common ground with the type of thoughts you've thrown up for me.
