This is a cool workaround, and I'm sorry to hear about the sad state of
IP networking in your area.

If you are using a configured tunnel from he.net, this is actually *not*
6to4 :-) - 6to4 is auto-tunneling, using 2002:xx addresses, relying on
an unknown-to-you anycast relay somewhere in the world which is mostly
impossible to troubleshoot.
Some migration mechanisms are going to stay with us for a while, and
"configured tunnels" (as he.net is offering) is one of them.
Other migration mechanisms work well for some, and do not work at all
for others, and you cannot fix it yourself because you rely on some
unknown third party services - that's what 6to4 is, and which is why
6to4 (with anycast relays) is something prople consider potentially
