Yes, LIRC is designed to be used with almost any TV or whatever IR remote. 
There is a huge library for various remotes, but you can also teach in the 
codes for new or unknown remotes. There is receiver hardware for the serial, 
the parralel or the usb port. LIRC is supported by various TV and video 
players on both Linux and windoze. With one receiver, you can use several 
remote controls in parallel and control different applications on the PC.

IrDA is for data communication between devices like mobile phones, PDA's and 
so on - it's just something different. At http://www.lirc.org/irda.html they 
say that IrDA hardware usually doesn't work with LIRC.

That I forgot to test :-(
On gentoo, there is a global "lirc" USE flag which will have to be added to 
the ebuild to trigger the compilation.

Thank you! In the future we'll see how big the intersection between 
Rosegarden-users and LIRC-users really is ;-)
