I don't see how it can be on the rise.  When FDT multihomed, we had to
arrange with both our providers to accept our route.  Why aren't all the
big providers putting distribute lists on their customer BGP peers?  The
access-lists should change infrequently enough that it wouldn't be a big
deal to maintain, and it would make the net a better place.  If I totaly
hose our BGP setup and announce crap to either provider, nobody will be
affected.  In fact, I think I did this the first night I setup BGP.
Nothing bad happened.

While they're at it, they could use the same data to setup/maintain
ingress filters.  Last I heard, Cisco had finally made it so that
non-logged extended access-list filtered packets are still fast switched.
