Agreed. You may start by adding either lirc "decoder" or mce. Both ways
will end on having the same result ;)

Historical reasons. It were simpler to start from drivers/media, as we've
started with some already existing code there.

My intention is to write one or two big patches at the end, moving everything
to drivers/rc or drivers/input/rc and renaming the structures. The point is
that a patch like that will force people that are working on the code to rebase
to the newer names, so I prefer to postpone it to happen after we finish with
the big changes. A change like that won't affect just the new RC code, but also
several V4L/DVB drivers.

Maybe the right moment would be during the next merge window, as all pending 
work for 2.6.35 will be already finished, and people likely didn't start 
working for 2.6.36. So, my intention is to write such patch during the merge
week, just after sending the pending stuff.
