If I understand you correctly, you want to filter inbound traffic from a
service provider to another based on what that service provider is
advertising and based on the decision process that we run.

How do you suggest we handle asymmetric routes?

If the problem is truely no router vendor make a router capable of
holding a fully filtered route table we need to tell the router vendors
this is a mandatory requirement or we won't buy their routers.  Remember,
once upon a time when no router could handle more than 30,000 routes or
64,000 routes.  Once the router vendors were told what was needed, they
built a box to meet that need.

It is not a given that no router will never support filtering a full
tier-1 ISP's route table.  Its just no one has made it a requirement.

Lets make it a requirement of the router vendors.
