Which is why Freenet6/Gogo6 has TSP and SixXS has AYIYA because
tunneling over UDP works fine, just like every other VPN product in the
market does (though most VPN products don't do IPv6 yet, it is coming).

Take a guess why these protocols exist ;)

That layer 1 personnel does not know about IPv6 just shows that the
company did not invest in IPv6 training yet. Their problem that they
need to resolve sooner or later and actually the bigger problem than
upgrading software or even hardware as those things just cycle out in a
few years time.

Let me guess, you are behind a NAT and expect protocol-41 to be
forwarded exactly where? Anyway, as stated above, just use TSP or AYIYA.

Having lived in The Netherlands for a long time and various other
places, I have never had a problem, even in hotels with broken setups,
to get IPv6 going. Heck it even works in most airports ;)

"IPv6 only" was the original plan of World IPv6 Day, but take a guess
how many phone calls would go to ISPs then and how much money folks
would lose when that would be done.
