After a port is open: - Trigger receive_connect on any socket connection event for the listening port - Send a basic "Bitcloud.js 0.1 PoC" on connection as a fill-in for eventual handshake protocol - Receive "Bitcloud.js 0.1 PoC" and confirm that the message is valid and compatible - { just to test, close connection after handshake } - Test by telnet at first.
