Seems that this entity (whatever it's called) isn't an endpoint at all,
so defining terms for endpoints shouldn't be relevant to whatever this
device is.

There's always more boxes in the middle..... although as long as they
don't have the DTLS keys, it's limited what they can do to the packets.

And I don't agree with Christer, so then we're two :-)
