To merge these 2 great threads, it is the case is it not that NAT is a great
way to avoid DDOS problems. I don't even want to imagine what the
billing/credit issues would be like if your always-on phone with a real IP
is used as a zombie in a DDOS. "Hey I didn't use all that traffic last
month....etc etc"

Who says a NATed host can not be a zombie?  Get the NATed host to read
an email virus.  The virus then coonects to an IRC channel that tells
the zombie when to spew.

Each phone would not spew much, but imagine you got 100M phones to do
your DDoS for you...
