    I thought so.
    FYI: a sane RC5 decoder doesn't depend on exact timing. Even seen
    a multi-function remote can control many different devices like TV,
    VCR, DVD and so on? From different manufacturers etc.

    Not sure what do you mean.

    There is no such thing as "being supposed to be used with PC".
    A space/mark receiver can receive data from any remote.

    If you want such setup - why not?
    If you don't - you can use lirc in both cases.

    Then keep it that way and let others use what they think is best for

    Now how hard is it to understand that?

    That could be the case if you were limited to "or". But we can do both.
