    Interesting question. For IR keyboards, if one could get line of sight on
    the IR beam itself, you could theoretically send another beam through it and
    get the data sent via the interferance patterns generated. You'd need the
    IR beam to pass through the interceptor-beam continually, as there has to be
    a detector mounted on the other side of the IR beam. Maintaining the
    beam-interception would be next to impossible.

    Another alternative might be a based on a detector for the scattered
    infrared light, as it passes through the air.
