In the following, I will keep in mind a scenario with 50 zombies, each
sending me mail forged to show 200 different users (randomly generated
names, like sldkjsfoiu(_at_)yahoo(_dot_)com) @ the same set of 50 different 
domains
(4 random users per domain). (Ie, the zombies have the same mailing list
to send to). Assume that each of the 50 domains uses a mechanism like
shown below; Assume the the random algorithm is the same on all zombies,
and it generates the same sequence of 200 unique usernames.


Haven't had time to think about the rest of your post(s). The above
makes me step back and go Hmmmmm.....  How can you call it random if
50 different hosts (zombies) come up with the same sequence of 200
unique usernames. By definition that would be nonrandom (not even
pseudorandom).

Or is there something I'm missing?
