hyp beam can be thought of as a drop-in replacement for nc, for those situations where you just can’t be bothered to set up a VPN or manually establish a path between two machines via traditional methods like port forwarding. It provides the user with a method of breaking through NAT and transferring data via the Hypercore protocol between two machines, peer to peer, anywhere in the world. Peer discovery happens via DHT/mDNS using a concept called Hyperswarm, not too dissimilar from what Bittorrent clients have always done; although its usage of mDNS is quite unique and cool.
