If you take a look at a Psiloc IRRemote config file, you'll see that it is in fact just an LIRC config file. I would guess that IRRemote is, like QtIrreco, just a skin over the LIRC server.

Unlike the LIRC server, I'm not trying to simulate individual remote controls. Each keyset in Pierogi represents an entire family of compatible remote controls.

However, a list of compatible devices is being compiled, and I am working on better ways of making entries in that list available in Pierogi...
