        I can tell you it's observable out there and if i use my home network
to follow default i can tell it is working through those devices at
least.

I agree with Randy it would be good if someone did this, it shouldn't be
too hard with ripe atlas and a provider deciding to announce something
like 240.2.3.0/24 to see if it can be reached.

        That's at least a decent measurement and report, but the client
side OS will still be a variable that is difficult to digest.  Not sure
how many people are running very old IP stacks.  This is another hard to
measure problem.
