    Ah.. Yes.. IIRC, when I was re-reading and re-reading the ADSL
    bandwidth limiting howto, the author did mention about shaping
    downstream bandwidth using the TCP window size.

    He also noted that there isn't any OSS software that's available
    to do that. If anyone has any idea, i bet a lot of ppl would be
    interested.
