None yet, but soon.  It all hinges on diffserv.  vBNS has comitted 
to providing RSVP over ATM.  Granted its a research network, but 
that is where the new technologies are proven.

In the meantime you can setup a traffic control capability using ALTQ
on your FreeBSD box.  I haven't tried dummynet but it is very popular
too.

Good luck,
George
