I was not raising a question, I was making a proposal.  Alessandro

What I meant by "realm" is very close to "administrative domain."

Sending realm sends to receiving realm.  a backwards-compatible (no
zero day) FUSSP must live on the receiving realm.

My proposal, that I guess I did not make very well, is:

For purposes of discussing the nature of a FUSSP, operations within a
"realm" (which is not at this point a well-defined term) should be
treated as a black box that has full information sharing within it.
