Colleagues, (with apologies for the cross-posting if you get more than one copy of this)
As you may have seen already, I'm working on a revision to RFC5451. A Proposed Standard "bis" effort always benefits from describing extant implementations. I know about the ones I've written, and about some very public uses of it (Gmail, Yahoo, for example). If there's anyone in this audience that knows of others, I'd love to hear about it. Reviews of the update are also welcome: https://datatracker.ietf.org/doc/draft-kucherawy-rfc5451bis/ Thanks, -MSK
