Hmmm, this is very interesting "bootstrapping" and false matching.

1. You are mentioning "1st generation QKD". Do we have now 2nd 
generation of QKD? Where the
"1st generation QKD" was applied and used? Nowhere! What are "the 
upgrades" and the new things
that "2nd generation QKD" has?

"Our 1st generation of Snake Oil was excellent, but unfortunately was 
sharply attacked by the people from
the field of Cryptology, and consequently it was not broadly 
accepted. But wait a minute, we have come now
with our 2nd generation of Snake Oil. It is even better than the 
first one, and it is cheaper. Previously if you
had to pay $100,000 per year for the secure link, now you have to pay 
10 times less i.e. only $10,000. That is
$90,000 saving per year, and imagine for what scientific purposes you 
can spend those $90,000. ..."

2. All optical networks are reality and nowadays are built even for 
home-end users. What that fact has to do with
"x-th generation of QKD"? In your post you are using the success in 
one field in Physics to
advocate possible acceptance of another (Quantum Cryptography). 
While, the optical physics has and will
have one of the crucial roles in modern and future Internet (taking 
care about the physical layer of the
network), QC is trying to offer better solutions (or replace some 
parts) of a well developed, well established,
and well applied scientific field (The field of Cryptology). My 
opinion is that it won't happen. Dead end.

Danilo!
