I once used LIRC hardware with drivers that needed to be reloaded after
suspend. All LIRC clients also needed to be reloaded, which I wanted to
avoid. As a solution, I added a LIRC meta daemon, so I had 2 lircd
processes running on one computer. Then, the LIRC daemon that handled
the hardware send the events to the meta LIRC daemon, and the clients
connected to the meta daemon. After suspend, I restarted the hardware
daemon, and the clients didn't need to be restarted to work after
suspend, because the didn't lose the connection to their meats LIRC
daemon.
