Subject: [TLS] Re: Is there any interest in an RFC on how to do cross-organization mTLS?
List-Id: "This is the mailing list for the Transport Layer Security working group of the IETF." <tls.ietf.org>

Would it be appropriate to write an RFC on how to make cross-organization mTLS work reliably and at scale? Would this group/mailing list be the right people to work with to make that happen?

You should also ask the UTA working group if they are interested.
