    Did you ever actually try to get a licence from IBM? While I too would far
    rather have seen BOCU-1 be freely available, the language says "IBM would
    like to offer a royalty free license to this patent upon request to
    implementers of a fully compliant version of BOCU-1"; if you'd been denied a
    license that would be surprising.
