TCPNet

This API allows for infinite cross range, cross server communication with the internet card.
 
It uses a external Lua server which requires luasocket (should work on both 5.1 and 5.2)
on ubuntu/debian you can use apt get install luarocks and then luarocks install luasocket
on windows: https://code.google.com/p/luaforwindows/downloads/list
others you will have to find/compile binaries
 
once you have a server set up and forwarded you can access it in OC with your computer's external IP (or localhost if you changed the tcp blacklist)
 

API

local handle=tcpnet.new([ip[,port]])

connects to the server, ip defaults to localhost and port defaults to 25476

handle:receive([timeout[,port]])

returns port,data
or just data if the port parameter is given

handle:send(port,data)

sends data to port

handle:open(...)

opens ports

handle:close(...)

closes ports

event "tcpnet_message",port,data

Protocol

every message and response is a table serialized
ports can be strings or numbers
it does serialize the data, but because computer.pushSignal doesnt support tables, my api wont allow them
but it is really easy to write your own api

{"send",port=port,data=data}

sends data to everyone listening on port

{"open",ports={[port]=true,[port]=false}}

open/close ports

{"message",port=port,data=data}

you receive this when you get a message

About luasocket, I know that you can install luarocks on OS X with both homebrew and macports, so you can run the server from OS X as well. 

 

Also, I don't really get what you mean with protocol. Is that what is returned by event.pull? 

[PixelToast 5]

no, thats the socket protocol

Nice! I'll take a look at the Pure Lua server and also take a look at cross-server communications because
That is just simply Fun!

Might have to make a multiplayer game for OC now... hm.
