On: WireGuard is now in Linus' tree

[hwh]

Can you please elaborate? As far as I see it, IPsec is encrypting traffic. IKE is for setup of security associations. What part of IPsec would do routing, and in this case: potentially multi-hop mesh routing?

IKE obviously does the key management part, it's part of IPsec in this picture.

There is no separate mesh routing in this scenario, everyone just uses normal internet routing and addressing.
