I am no ipfw or dummynet expert, but I read some of your other posts and
noticed that you are using 3200 rules and 3200 pipes, and are matching
the mac address.  Do you have to match the mac, or can you do this by IP
address?  According to the IPFW man page, if you specify a mask with
your pipe configuration, you can match on every bit which would
dynamically create the pipes based on the size of the parent pipe.  I
think it would be something like...

ipfw pipe 1 config bw 512kbit/s mask src-ip 0xffffffff
ipfw pipe 2 config bw 512kbit/s mask dst-ip 0xffffffff
ipfw add pipe 1 ip from any to any in
ipfw add pipe 2 ip from any to any out

Like I said, I am no expert, but figured I would spew this to the list
anyway.
