The IETF DANE WG.  Their initial focus seems to be TLS,
but the same approach ought to work fine for IPsec
(and was always what I expected to happen, although
I thought it would have happened sooner. :-)

No.   See above.  Folks are expected to have DNS,
which is already an expectation.

To Mark's point at the very top, tunnelling is indeed
one method to permit options/headers/new-protocols
to be deployed, but it assumes cooperating endpoints
who can encapsulate/decapsulate as appropriate.
