Maybe I ate too much moose but I don't agree with you, you all said your opinion and in fact it did not helped me much in my technical evaluation.

nihil, even if I could sell you something I would'nt, I am a communist .

Ethically
I must say I am proud of you. I think it is very important to ask us the meaningful question of why and what they will do with the technology we develop. But it is a promethean world (free man with science?), and you are a part of the evaluation phase so do your best

Technically
I don't think the relation between anonymity/privacy effort and detection cash-power is linear (I hope I will find my curve soon).
The anonymous mail-ftp system seem nice and I will come back to you on that subject if you care.

Thanks for all your comment
