I would like to have these operate this is not true -- you can do what you want trivially with dummynet, which lets you limit the bandwidth per-flow by using masks on pipes, and you can aggregate flow as you need using masks appropriately on addresses and ports. Read the ipfw manpage. What you might not like is that you need root privs to configure ipfw/dummynet, but that's another story... cheers luigi > only on a socket fd that I designate.
