/*
|

* The start of a port forwarding service.
|

*
|

* This is just a very rough example of what might be required for version 1.
|
||||
*
|
||||
* FIRST VERSION:
|
||||
*
|
||||
* listen to a single port and send data with a single RS peer.
|
||||
*
|
||||
*
|
||||
* SECOND VERSION:
|
||||
*
|
||||
* enable multiple port forwardings.
|
||||
*
|
||||
* each forwarding consists of a 'port, peerId & Connection Id'.
|
||||
*
|
||||
* THIRD VERSION:
|
||||
*
|
||||
* add broadcast/multicast forwardings.
|
||||
* i.e. data gets sent to multiple peers.
|
||||
*
|
||||
* each forwarding with then consist of 'port, connectionId + list of peerIds'
|
||||
* NOTE: version 3 needs some thought - might require a master host
|
||||
* which distributes to all others.... or other more complicated systems.
