wow, first I've heard about this. How does this differ from the Nerves project, which also boots directly into the Erlang VM?

Nerves boots into the ErlangVM, but runs on a buildroot Linux. This makes it possible to run on a wide variety of hardware, but with the associated baggage.

GRiSP uses RTEMS[0] as its base which should make its performance more predictable.
