the expensive way to do DDoS ?

[Darren Reed <darrenr () reed wattle id au>]

If you had money to burn, how many el-cheapo pc's would you need to install
at POP's around the world such that you had a virtual army out there that
was yours and from which you could send forged packets whenever you like?
(just how many ISPs are going to bother checking, eh?)  All you have to do
is muddy the path of who the ISP thinks owns those boxes and yourself in the
event that someone works out which boxes the packets are actually coming
from...would 1000 be enough ?  (Are there even that many POPs ? :)  Maybe
too expensive for a teenage hacker, but not the mafia, CIA, etc.
