Physical port shaping/throttling

[emigrating]

Perhaps I'm missing the obvious, but I need to throttle traffic based on NICs. I'm not really bothered about shaping as such as that can be handled down the line from me but it seems to be the closest I get in pfSense?

Basically - I have 1 WAN, 1 DMZ and 4 LANs. The DMZ and one of the LANs should always be able to use 90% of the WAN linkspeed, the three remaining LANs should be able to utilize 15% each of the WAN speed (for a total of 45% if they are all "full").

I know this can be achieved (sortof) by Penalizing an IP or Alias, but for various reasons I won't go into I need to do it per physical port on the pfSense box - is this at all possible? Either via the bounty shaper or the alpha 1.3 release?
