Infra-red remotes simply work by pulsing a infra-red led at a certain
frequency (pretty easy).  There is a remote out there made by GE for
around $100 (I think) which can be taught remote codes (you put the
GE remote in learn mode and then press the appropriate button on the
remote you want to substitute for).  After teaching the GE remote
can then send any of the remote codes you taught it.
