I'm questioning whether the added complexity is worth it, when I doubt the vast majority of users would take advantage of it, and it can already be done in userspace. Although... Damn. The userspace approach would only work if the device were passing raw IR to userspace, so in the in-kernel decoding case, yeah, I guess you'd need separate input devices for each remote to use them independently. Meh. Doubt I'd ever use it, but I guess I'll concede that it makes some sense to do the extra work. >> You just need to send a tuple that contrains the keycode plus some kind of >> id for the remote it came from.

In this specific case, IMO, the default keytables should map the power button to KEY_POWER2. > > Perhaps we should clarify something here.

Yes, but several bundled IR's have a power button. By default, it doesn't make sense to use it to turn the machine off, so KEY_POWER2 is a good option. > Otherwise, yeah, I'm going to wind up with my htpc powering off when > I hit the button on my harmony remote that is supposed to turn off my tv and amp.
