Every time I've looked at setting up distributed VPN I've wanted layer 2, I haven't used WireGuard yet but apparently it's layer 3. I would love to be able to connect remotely and have my newly connected machine act like just another machine on the LAN. That in turn makes all kinds of other network-related operations simpler and homogeneous, in that the remote property of the connected machine(s) is abstracted away.
