You can do this if you patch the kernel and iptables so it supports the imq
device. An imq device is a virutal device and you can put packets with
iptables in it. You can also shape that device.
In your case, you need to create 1 imq device and redirect packets from both
directions to port 80 to it. And add a tbf (or cbq or htb) qdisc to the imq
device to limit the traffic to 5mbps.
For a link to the imq device, see the faq page on www.docum.org.
