Hi Ted,

By “NM” I think you mean “Mobile Node?” That’s not really one of the use cases we’re talking about here. Or am I missing something?
Or, just call it a (mobile) “Stub-Network” – I think we are talking about the same
thing here.

In any case, you’re presuming some kind of trust establishment for non-router nodes, right? SEND only talks about trust establishment for routers. And, let’s be frank, doesn’t actually give us enough operational guidance that we would expect what _is_ said to be generally practicable.
OK, the specs I have been working dip their toes into the SEND pool but maybe they
should be updated to dive in completely? With an adoption call in progress, I don’t
know if it would be a good idea to make changes right now but be assured that it
will be added to the TODO list – would that be acceptable for now?

Thanks - Fred
