With this initial release, they seem to be targetting boards like the raspberry pi that have spi ports or gpio ports that people have made python modules for that are resonably abstracted. From how everything's laid out, it looks like you're supposed to have a source actor which does the low level work, like polling the gpio ports, and from there, passing the message to other actors which may be on other servers. I'd like to see the spec hashed out a bit better, because right now, it seems that there are too many bits of it that only have code as documentation.
