I can not answer abut pf but I'll say that if I were using ipfw I 
would use dummynet to rate linit the speed that the incoming packets 
were passed on to the client macjines and I would make that limit 
just  alittle slower than the incoming link's real speed.
that way the linit would be In my machine instead of in my ISPs machines.

If pf has a similar mechanism to dummy net then you may be able to try 
that.
