Yes, all IPv6 nodes (also 6LoWPAN ones) can be addressed and accessed. I 
interpret this requirement to mean that you should tunnel IPv6-in-IPv4 over

whatever IPv4-only parts of the Internet you come across. There are
probably 
half a dozen other alternatives as well but that is the most
straight-forward 
from my experience.

You are right, should be clearer.
