Hi,

I'm reading this thread with great interest.  Thank you (plural) for the
very informative conversation, I think I learnt a lot.  But now I
somehow lost the point, please correct me if the following is wrong.

It looks like having lirc_dev (or a similar raw interface) is a must.
It could be disguised as an input device, or changed in various ways,
but is it worth the effort?  As I understand Christoph, he does not want
to do so, because he finds it wasted work, and also there's already a
*single* user space daemon using it and doing everything users could
want.  Except for plug&play.

On the other hand, a one-liner could make in-kernel decoding possible,
so those who haven't got lircd running could have plug&play easily, if
somebody writes the necessary in-kernel decoders to feed the input
subsystem (which lircd also does, through uinput).

But even if you can't find anybody at the moment to write those, this is
still good stuff (I don't know about the code), which is hurt by being
developed out of kernel.  Is there any reason to keep this so?
Admittedly, I don't know why /dev/mouse is evil, maybe I'd understand if
somebody pointed me to some reading.
