Seems interesting, but I think it needs some use case examples to show how it differentiates from a tunnel, VPN etc. As an example, would it be the right tool to access IoT data from small sensors (and actuators, therefore two ways) in a private LAN from external machines, including mobile, on untrusted public networks? Or what if I wanted on all my laptops a shared directory that replicated on all machines what is being written on one, no matter which networks they're connected to, NAT etc. etc...
