For bandwidth, ALTQ already provides that. It should be pretty easy to
implement a discipline to do that for packet rates as well. Note that it
only applies to out-going (and indirectly for forwarded) traffic.
So, PF + ALTQ does not allow for incoming bandwidth limitation?
It can technically, but you can't force the other end of the line to 
control packet output according to rules on your end. What works is 
limiting recieve/forward buffers so your host sends e.g. source quench 
messages earlier, but you can never be sure the host on the other end 
cooperates. Especially not in any complicated priority scheme. The same 
thing applies for any other solution for bandwidth limiting, be it 
dummynet, wondershaper, altq or whatever.
