I think we're eventually going to want to let rc-core create a chardev 
per rc device to allow for things like reading out scancodes (when 
creating keymaps for new and unknown remotes), raw timings (for 
debugging in-kernel decoders and writing new ones), possibly also 
ioctl's (for e.g. setting all RX parameters in one go or to 
create/destroy additional keymaps, though I'm sure some will want all of 
that to go through sysfs).

That same chardev could also be used to implement TX, once a suitable 
interface has been fleshed out. The end result might not look exactly 
like lirc...
