At the simplest, this document explains that radio transmission is not 
transitive. Should be obvious, but experience has shown that it's only obvious 
after it's said.

Why is that important? Because it means that simple broadcast wireless 
transmissions do not satisfy the assumptions that e.g. ND is built on.

So you can't just hook a host up to a broadcast wireless tranceiver and expect 
it to work. A router, on the other hand, might work. (Each assuming other such 
devices.)

So that's an important difference between hosts and routers in this 
environment. And I think this document needs to say it, at least at some level, 
as that's a key motivation for some things it says. Without making that point 
there's a danger of a reader saying "Radio transmission isn't transitive. So 
what?"

How to make host devices (as opposed to hosts on devices that also have router 
functions) work is another matter, which may or may not be considered here. 
Having a little bit of router, maybe just enough to ignore some direct 
communication with other host devices, might work, for example.

All in my opinion of course.
