We're a bit closer to something sane, now. We can wrap, but not unwrap, packets. Asymmetric encryption is *big*. encrypted text with a 4096-bit RSA public key is 512 bytes. We can't fragment yet. Fortunately, this isn't an infinite regress once we *can* fragment. Performance is still a big question mark, of course. There may still be endianness issues hanging around. The eid<->rloc map is almost certainly far, far too slow to be of any use in the real world.
