BGP-edge filters don't help with customer-to-customer packets within the
same ISP BGP autonomous area. So you would need CPE customer-edge filters
anyway. A small ISP might be able to handle individual customer filters on
their backbone routers, but that way leads to insane network engineers.
See Barry Greene's page for the list of all the pro's & con's of different
alternatives. There are very few new ideas, just new people rediscovering
old ideas.
