The TV Remote Control program at http://www.pdawin.com can learn the Lego Remote just fine. The current version of their software is voice activated. You can also make your own controller skins. With my iPaq (3600 series Pocket PC), I could control a Scout or RCX up to 10 feet away (depending on where the bricks were facing). After a little more research, I found another TV remote program at http://www.pyramidpeak.com/universalRemote/universalremote.html. I haven't tried this one yet, but there's a link on that page that gives a seemingly vague explanation of how it works. Seeking a better description, I found these two pages explaining how this is done: http://www.veg.nildram.co.uk/remote.htm http://notch.mathstat.muohio.edu/html/Infrared/x1923.html <-- much better resource I think the TV remotes for PDA's are using "3-wire raw" mode of IRCOMM to accomplish what is described in the previous two links, but I'm not sure. All the other modes of IrDA seem to wrap the data packets. Check out http://www.irda.org/standards/pubs/ircomm10.pdf for more detail.
