+# RVPN Server
+
+A Poor Man's Reverse VPN written in Go
+
+Context
+-------
+
+Even in the worst of conditions the fanciest of firewalls can't stop a WebSocket
+running over https from creating a secure tunnel.
+
+Whether at home behind a router that lacks UPnP compliance, at school, work,
+the library - or even on an airplane, we want any device (or even a browser or
+app) to be able to serve from anywhere.
+
+Motivation
+----------
+
+We originally wrote this in node.js as
+[node-tunnel-server](https://git.daplie.com/Daplie/node-tunnel-server),
+but there are a few problems:
+
+* metering
+* resource utilization
+* binary transfer
+
+### metering
+
+We want to be able to meter all traffic on a socket.
+In node.js it wasn't feasible to be able to track the original socket handle
+all the way back from the web socket authentication through the various
+wrappers.
+
+A user connects via a websocket to the tunnel server
+and an authentication token is presented.
+If the connection is established the socket should then be metered and reported
+including total bytes sent and received and size of payload bytes sent and
+received (because the tunnelling adds some overhead).
+
+### resource utilization
+
+node.js does not support usage of multiple cores in-process.
+The overhead of passing socket connections between processes seemed non-trivial
+at best and likely much less efficient, and impossible at worst.
+
+### binary transfer
+
+node.js doesn't handle binary data very well. People will be transferring
+gigabytes of data.
+
+Short Term Goal
+----
+
+Build a server compatible with the node.js client (JWT authentication)
+that can meter authenticated connections, utilize multiple cores efficiently,
+and efficienty garbage collect gigabytes upon gigabytes of transfer.
