Not to downplay it or anything, but it is "just" the normal Erlang BEAM VM compiled together with the real time OS RTEMS (which basically implements all POSIX things that the VM needs). Of course, getting it to work needed a lot of research and and experimentation, but the end result is surprisingly simple for what it is. The maniac/genius part is coming up with the idea in the first place and actually pushing through until it works, not many people have the stamina and focus for that. Source: I was part of the original core team, and I developed the first version of the Erlang support library and runtime.
