+1

I agree completely.
This way we can make lirc to recognize any remote.

Don't yet have a general receiver, but when I have one, I would like to use my remotes,
and who knows what protocols they use...


Best solution is to make new input layer message, a raw PCM data.
or, you can even keep the daemon, but make it inject input events back to input system.

The only think I don't like at all about lirc is that you need special library to talk to it
while I want remotes to be used as a keyboards.

Btw, one can write a lirc client that does the above, but this is hackish.

Some standard ir protocols can be decoded in kernel, but there should be standard (not debug) way
to do so in userspace.

Just my .02 cents,

Best regards,
