I use OpenWRT for my neighborhood WiFi Internet. The GPIO pins on
OpenWRT devices have been re-purposed for memory cards, so if you
disregard the wireless and RTnet, could this be close to what is needed?

I visited the ETC site and it reminded me of lighting controllers. I am
a part time roadie for a friend's band, and at one time we were looking
at getting a dimmer for our lights. Cruising eBay, I found a lighting
controller, and with research found that it used standard sound cables
and I believe a serial protocol as an input. The band isn't successful
enough to afford a real lighting system, but maybe some day. It would be
fun to take apart ... I mean use one of these controllers.
