I have just spotted it and agree it has some very nice properties which seem
complementary. Not least:

* asynchronous message passing both intra and inter node built into the
kernel core,

* built in resiliency across multiple Ethernet links between nodes (various
methods including send on all and receiver selects the first to arrive, send
via another node..).

* hard real time.

* Claimed full POSIX compliance.

I'll have a go at compiling OTP on it if I get some time. It seems it might
be worth another look.
