RFC2767 implementation and deployment experience?

["Templin, Fred L" <Fred.L.Templin@boeing.com>]

Hello,

Can anyone tell me whether RFC2767 ("Dual Stack Hosts using
the "Bump-In-the-Stack" Technique (BIS)") has been widely
implemented and/or deployed in operational networks? Do you
further expect that it will play an important  role in IPv6
transition? (Originally sent this to the authors, but it
bounced.)

Thank you,

Fred
