Only if you do it the hard (and less useful) way: using the kernel's
built-in keyboard driver (which, interestingly, is often considered the
easy way :).

No problem, indeed.

I'm using the ATI Remote Wonder. I like it because it provides a bunch
of buttons and is LIRC-compatible. Many people using the RW are using
the kernel's built-in "keyboard" driver for it. The main problem with
that is that each button sends a keycode, so you have to map your key
combinations for each application with which you want to use the remote
(which means you start memorizing your non-default settings for use with
a real keyboard and--depending on how you set things up--you may lose
functionality or break applications with bad key configs--i.e. as new
commands are added to new versions, they may conflict with your remapped
key configs). Also, LIRC provides a means of doing virtually anything
(from sending a message to an app to sending keystrokes to running
scripts/applications to ...) whereas keyboards provide only a means of
So, I highly recommend use LIRC.
That being said, I also recommend not getting a combination RF/IR remote
(i.e. like the X10 Lola--which is basically the ATI RW with IR modes).
With that, you would have to have "modes" (i.e. TV, VCR, Myth, DVD,
etc.) so the ("stupid") remote knows what to send and how to send it and
a ("smart") person who knows which buttons to push in which order.
Instead, you can use one remote (RF or IR) and an IR blaster. Then, you
program the ("smart") computer to do what it should when a key is
pressed. For example, you press the "TV" button on your remote, and
your computer sends a "discrete" power on command to the TV and the
Audio/Video receiver using the IR blaster, and sends the appropriate
message for the LiveTV jump point to Myth using LIRC (zero to LiveTV in
0.25 seconds). You press the volume down button, and your computer uses
the IR blaster to send a volume down to your A/V receiver (instead of
trying to control the volume in software--which is especially wrong with
digital sound). You press the "Music" button on your remote, and your
computer sends a discrete power on command to the A/V receiver and a
discrete power off command to the TV (assuming you don't want your TV on
during music playback) using the IR blaster and sends the appropriate
message for the MythMusic jump point to Myth using LIRC. With this
approach, you're only limited by your imagination (and, to some
extend--barring additional software--the number of buttons on your remote).
