Hi Luca,
I _love_ the sound of that. Hopefully the AF9015 I've got does the same 
thing, because that would be ideal for me.
The remote that came with my dongle is  a pathetic little thing, which 
renders the remote functionality of the dongle useless, unless it can be 
used as a generic lirc device which would mean I no longer need a 
separate serial lirc receiver.
I personally feel that letting lirc do what it's good at is a much 
better way to set up drivers/system if at all possible, especially as it 
gives flexibility to use whatever remote you like.
It really isn't a problem that you need lirc, as most of the time you 
use it anyway for remotes. Even when the remote gives a /dev/input 
keyboard like functionality it's common to use lirc to then set up the 
keys how you want.
