Eric, a quick follow-up:

1. I'm using kernel 2.4.17, and have compiled shaper support in as a module.
2. apt-get install shaper
3. insmod shaper
4. shapecfg attach shaper 0 eth1
5. ip addr add dev shaper0 192.168.2.2
6. ifconfig shaper0
shaper0   Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          inet addr:192.168.2.2  Mask:255.255.255.0
          [NO FLAGS]  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:10
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

That's as far as I've taken it (need to think about a test scenario) but it
appears to work with this kernel. I'll let you know if I'm able to do much
more with it.
