Paul,

Try the mailing list at ima@ietf.org, which belongs to the
(now-closed) WG that specified the standards for those
addresses.  You will have to sign up for the list before
posting, see <https://www.ietf.org/mailman/listinfo/ima>.   If
that is a problem, let me know and I'll forward your note and
ask people to contact you directly.

I will also forward, under separate cover, an announcement that
showed up earlier today about the release of commercial products
that support those standards.  As far as I know, everything
before it has been primarily a testbed, but there are several of
those.

good luck,
   john
