While we may not know the scaling characteristics of the solution, do we
at least know what would be a desirable objective target for sustainable
deployment?

Does "much better" accommodate our desired engineering targets for
long-term?  What are those?

Twitter may be more real-time (only half kidding :-)

Again, if we're engineering here for the future and stable standards then
what are the desirable long-term system scale objectives for the RPKI?  I
think this is a pretty reasonable question - when this is fully deployed
in n years, whatever the timeline is, what do you believe will be the
number of objects (CRLs, EEs, ROAs, Manifests, size, etc..), RPs,
frequency of updates, etc.., given the operational and design experience
you have thus far?

While I suspect some clever response here, I'm being sincere with these
questions, particularly if we're baking this stuff into standards track
protocols.

Thanks,
