that's still too simple: If you are a hoster, then a single hijacked
machine from a single customer will have all your other customers
quickly blacklisted as well.

IMHO blacklisting IPv6 addresses is pretty much a hopeless effort.

Make it a law -- and one internationally established and enforced:-)

Until then: Stop offering flatrates (not Spacenet, but all ISPs).  As
soon as people have to pay for the spam their machines "accidentially"
send out the'll be slightly more careful about securing their boxes.

Not that I have too much confidence in any of these approaches...
