And just look at some of the options the Linux kernel (2.6.22) provides
just for congestion control and quality of service:

    --- TCP: advanced congestion control
    <M>   Binary Increase Congestion (BIC) control
    <*>   CUBIC TCP

Someone insanely geekier than I am ought to be able to squeeze all the
delays out of this given all those options.
