Right. For the DTLS I was thinking we'd do the handshake in userspace
and then hand the UDP socket down. At that point it's basically the same
as ESP with the bytes in a slightly different place.

So I really am looking at an option for "here's a UDP socket to send
those tun packets out on, with <this> encryption setup" as the sanest
plan I can come up with.
