I support adoption, and I am willing to try to create a validator
implementation based on OpenBSD's rpki-client. During implementation
feedback in the current document & questions can be shared with the
group, hopefully increasing the document's readability for future

A particular use case stands out to me: the PeeringDB platform could use
RTAs to validate ownership of PeeringDB "IX" and "Network" objects,
greatly increasing reliability of its user-submitted database, while
further reducing friction in its onboarding processes.

I would like to recommend the authors to include a copy of the RFC 7942
section 2.1 boilerplate text in the draft (optionally to be removed by
the RFC Editor) to help track implementations. Please make it clear
the 'signer' and 'validator' components are implemented separately.

Congratulations to both APNIC and NLNetlabs for already having
implemented such an incredibly innovative application of the RPKI. I'm
certain RTAs will prove to be useful in a myriad of B2B processes.

Kind regards,
