    Hello,
            I am looking at methods to rate limit a single socket to a specific
    pipe or rate with FreeBSD. I would like to make an Apache module that
    could do its outgoing rate limit *in* kernel, making the module very
    simple, and more accurate by using the kernel todo the rate limiting.

    I have been looking at Dummynet and pfil_hooks, but these seem to
    operate only on an entire interface. I would like to have these operate
    only on a socket fd that I designate. Ie a special setsockopt() would
    put socket x into pipe a. This pipe 'a' was setup ahead of time to only
    allow 512 kb/s.

    Is this possible with FreeBSD? Do you have any suggestions on the best
    way to proceed?

    Thank you,
    -Paul Querna
