Looking at http://www.lirc.org/html/technical.html suggested to me that
you can could do that via one /dev/lirc
The top half of the diagram allows concurrent use of each path; however
the bottom half isn't concurrent.
I had tied that together with the fact that lircd could be compiled with
multiple driver support and I misunderstood.
FWIW, I think a single lircd could handle it all as each REMOTE could be
associated with a device in the config file - but it's not :)

No, I was using the console.
