Playing devil's advocate for a moment...

Even if an IPv6 network is 10 times as insecure as a similarly configured IPv4
network, they are both as dust motes in a tornado given the incredibly insecure
state of most endpoints on the network.  Last I looked, there's a lot less
scanning of subnets looking for probably-firewalled-by-default-anyhow systems
because it's just so much easier to to whack the systems in a drive-by attack
when the system visits a compromised web page...

And the "ZOMG they can overflow the ARP/ND/whatever table" is a total red
herring - you know damned well that if a script kiddie with a 10K node botnet
wants to hose down your network, you're going to be looking at a DDoS, and it
really doesn't matter whether it's SYN packets, or ND traffic, or forged ICMP
echo-reply mobygrams.
