    You should be fine but you will need two SEPARATE instances of lircd 
running. Also, my experience has shown that you do not want both 
instances of lircd changing channels at the same time. On my system if 
they change channels at the same time both instances of lircd die and 
only about half of the IR commands make it to the cables boxes. I solved 
this by having one of the channel change scripts sleep three seconds 
before changing the channel. This might not work so well for you if you 
use live TV alot, which I hardly ever do.
