This brings to mind another project I saw, 
DDoS filtering via BGP feed....
BGP input and then OSPF or RIP or EIGRP redis to 
firewall etc..
IE I pull it in to a small "one-armed" router sitting on
the network and then redis to other specific points...
in some cases I may not want to prevent some traffic from certain 
parts of my network, but want it filtered on other parts.
