I'm trying to stay as close to the OS layer as possible with my options, so I would prefer to limit the role of comprehensive software like OpenVPN or what ZeroTierOne appears to be. I actually found this interesting github project, which provides a simple solution for what I'm trying to do... https://github.com/vsergeev/tinytaptunnel Unfortunately, it's written for Linux... and... in go... but the README at least gave me a couple more ideas to look into. Feel free to keep coming with the suggestions if anyone has anymore!
