Speaking as regular ol' member.

Too bad you couldn't make the meeting, Danny.

This is in bgpsec path validation and the signalling would go no further than the bgpsec path validation would go.

A method of "signalling" that was mentioned was the validity periods on the router keys so all RPKI info needed would already be available. Other means were also discussed, no decision made.

Shouldn't this problem be solved in the resource certification infrastructure (i.e., RPKI) - signaling RPKI freshness in BGP and distributing to literally millions of routers seems like a REALLY bad idea to me.
