What about ripping out the IR and jumping right to Blue Tooth. This way the NXT
can directly control 3 or 4 trains wirelessly (more if you use a hierarchy), as
well as many laptops and smart phones!
I know tha Blue Tooth is designed to be low power and inexpensive; for cell
phone/headsets, mice and keyboards etc.
