For the taildrop author: I could see potential on this to be used in the enterprise blockchain area with a condition: make it easy to setup a virtual network in wich each member is manually approving public keys of the consortium members. Working with docker/kubernetes will also be good. Contact me (taildropfromhn at axiologic.net) if you want details. We will love to use such a VPN setup in a real blockchain project for pharma industry.

For others: therr others that will appreciate the better security offered by using public key cryptography while still having a lightwight but decentralised setup?
