    There's no conflict. LIRC is the Linux remote control
subsystem just as alsa is the Linux sound subsystem & video4linux
is the vidcap subsystem.

    If an app isn't aware of any of those subsystems it won't be able
to use any of them and you will have to cobble the data into them via
some other means.

    The only real "shenanigan" is the relatively crude daemon
associated with lirc. Everything else is stuff that you really
can't get away from. You're going to need device drivers, a
layer to map what's on the remotes and another layer to map to
what exposed functions in the apps.
