I'd perhaps reword that as "no global tunneled infrastructure". And even
then I'd be a bit hesistant: tunneling across short distances is not that
big a deal, but adding different administrative parties can make it more
and more difficult.
Solutions like ISATAP can provide rather good performance in a limited
case; connections outside of the "site" could be native v6.
