Given that there is a pairing option for the Keyspan RF Remote for 
Front Row with the two buttons on the receiver and the remote, I'd 
think that these two use some sort of ID internally. Yet, I really 
can't tell how that feature works and whether it supports several 
remotes side by side. I only own one of these remotes and thus can't 
try.

I also had a look at the driver sourcecode and the RF Remote for Front 
Row driver currently only supports one receiver at a time. Changing 
that shouldn't be too much of a deal, though - I just need to find the 
time for that.

How would you put two of these remotes to use?
