[ipv6hackers] Implications of IPv6 on network firewalls

I also have strong doubts that IPsec will be used everywhere to everywhere: too complex do and it would also make firewall and IPsec blind which is probably not what some network/security people want to do.

Regarding the secure printing, like Marc I have seen applications where it is more about being physically present when the pages are printed and not so much about sending encrypted data to the printer.
