it won't be your competitors who suffer though...it would be the networks
that someone is trying to hijack that would see traffic/reachability
problems.  granted this would be limited in scope to those networks which
are not filtering, but as we have seen numberous times on this list and 
others, filtering isn't universal or equally applied.  

while i don't agree with the methodology covad is using, i can understand
their position.  and if it had happened to me, i probably would have done
the same, albeit for a shorter time frame...you and i are free to filter 
our networks as we see fit (or are contractually obligated), so if you
want to filter at /18, go for it.  i however will urge everyone
(especially my competitors) to filter because it is good for them and good
for me.
