Rate Limiting on Cisco Router

Pretty funny and good stuff....since no one really acheives true 100MB speeds anyways, then
a 100MB port might actually traffic shape itself naturally!!! I forget what the actual speeds truly are...
is it 80% advertised speeds?

I'm not sure which is cheaper but I think Juniper has some low end Netscreens you can try also
that have traffic shaping features.....
