If it weren't so dangerous, I'd suggest a "hyperweight" that
overrides prefix length.  Hear bogons from route server, set
hyperweight high enough to override longer prefixes, and set the
next hop to null interface.

Things like this return us to separation of routing and
forwarding:  Should BGP munching and fancy route-fu be performed
on a flexible, customizable *ix box, then fed to the actual
forwarding machines?
