Receiver pings the server with the IP and port

Receiver getsthe ID and the user may share the ID

Rec - [IP, Port]
Serv-Rec - ID
Rec-Send - ID (private)
Send - [ID, Metadata]
Serv-Send - [IP, Port]
Serv-Rec - Metdata

Sender pings the server with the conn ID and the MetaData and receives back the IP and port

Maybe use websockets instead???
