I stated this in the beginning of the discussion, but here goes again:

I want to protect ISP equipment from outsid/Internet DDOS attacks. I 
foresee proliferation of basement/FTTC L3 switches (ASIC forwarding, small 
TCAM, small CPU) with ethernet/vdsl2 PHYs, and I want to be able to 
rate-limit traffic coming in from the internet to these devices (also my 
core).

Therefore ISP equipment needs to be in separate IP space from customer 
equipment IP space. This also applies to SOHO market.
