This remarks shows that the problem is around for more than ten years and 
that no one found a satisfactory solution in using the present system. 
Would this feed back from real world not be enough for us to understand its 
'cybernetic' (true meaning) lesson : the current mail system model is 
inadequate.
Question now is : do we have to investigate a new one? or can an 
architectural change/addition may elegantly address the case? probably a 
mix of both due to the existing e-mail system use. ie a new e-mail system 
with a retro-compatibility with the current one. Or would it also be a new 
TCP/IP design, compatible with the old one? Or/and a new IPv6 compatible 
with the old one?
May be Dick Clarke will tell us next week how much he wants to invest into 
such a Nextnet?
