No, what we need is a protocol that can do *secured* distribution of
filtering info net-wide.  Otherwise, some bozo is going to accidentally
inject a flter for 127/8, causing as much fun as the announcement of same
a few years ago.  And I'm *sure* there's at least a few people on this
list that would be *very* tempted to inject filters for RFC1918 space
for the benefit of those providers that don't egress filter it currently ;)
