In the past, this question came up a few times, and Alonzo decided to
try it.  He also came to the conclusion that it couldn't be done because
"the range of the LED was only a foot or two."  He was wrong.  Any of you
with IR printers tried running your frinter from 5-6ft away?  Works, doesn't
it (if you've got decent battaries on the printer)....  Although the
48's receiver (I'll say it again, RECEIVER) is very low powered, just like
every learning remote on the market, it has a decent TRANSMITTER.  

The code that is needed is how to get around the error correction coding
on transmit and receive.  When data is received from a remote, a good bit of
it is stripped out as it is received - what the calc. thinks is error 
correction bits.  This would be fine, if when it sent the codes again it
placed the same code back into the data....but it doesn't.  We need a way to
access the ir ports directly, around the error correction gear.
