Unless you have access to your ISP's equipment, you can't really traffic-shape downloads anyway -- just uploads.

You can, by dropping ACK packets. Works surprisingly well.

I find that it works very well if you put an outgoing queue on the inside LAN port of your router and force it to schedule packets at the desired download rate.

This makes your router the bottleneck. This also lets you do RED with ECN and other things. Doing a traffic police rate drop on the WAN port just isn't as good.
