Hi,

A bit more about SEND.
I was the CISCO IPv6 engineer who did the dev-test for SEND. I wrote the
test plan and all the TCL scripts to test it all and I also developed the
template to decode the protocol with the Cisco Internal tool...

I would have love to see Microsoft keeps its word and implements it in Vista
as I heard they will but once we (CISCO) developed it, then Microsoft did
not :-(

I wrote this post about SEND:
http://www.fastlaneus.com/blog/2011/08/30/secure-the-ipv6-network-access-wit
h-secure-neighbor-discovery-send-rfc3971-and-cga-rfc3972/

I believe that there would be no protocol safer than IPv6 if SEND was
implemented by Microsoft and Apple... It's a shame they did not!

Having PKI is not a big deal. We get a certificates in France in 10 minutes
from the French Tax when we do our tax return online ! And you only need to
do it sometimes. You don't need a new certificate everyday !

You also need strong time synchronization to make it work but this is not a
big issue neither.

The only big problem is that neither Microsoft neither Apple implemented it.
