README

P2P module
===========
 (Techniques to get over NAT)
  - UPNP implementation
  - DMZ to be used if UPNP does not work
  - Port forwarding for future release

 (Discovery of Nodes)
  - Connect to reliable connection (that has some knowledge)
  - Check if the connection is still open (If not instruct the server to remove from table)
  - According speed tests
  - Send list of servers connection open
  - default 100 MB (to store tables of ip records)
