Yea, really, people do it everyday, it is call VPN.  It is not 
exactly the same thing, but not that different.  Today, 
especially with cheap high speed broadband, how many 
companies are connecting their remote offices with Internet 
VPN.  At the University of Minnesota we are, and we are even 
using globally accessible IPv4 addresses inside the encrypted 

Today many people are implementing IPv6 inside of tunnels of 
one kind or another, 6to4, 6over4, 6PE, 6VPE, they are all 
tunnels over their dominant network technology, IPv4 or MPLS.  
People tunnel SNA and other legacy protocols inside IPv4 
today too.  

Why is it so hard to believe that some day we will tunnel the 
legacy protocol call IPv4 a dominate protocol called IPv6?
