Running a "full-featured" REPL using a net.Server and net.Socket
var net = require('net')
var sock = net.connect(1337)
process.stdin.pipe(sock)
sock.pipe(process.stdout)
sock.on('connect', function () {
process.stdin.resume();
process.stdin.setRawMode(true)
})
sock.on('close', function done () {
process.stdin.setRawMode(false)
process.stdin.pause()
sock.removeListener('close', done)
})
process.stdin.on('end', function () {
sock.destroy()
console.log()
})
process.stdin.on('data', function (b) {
if (b.length === 1 && b[0] === 4) {
process.stdin.emit('end')
}
})
var repl = require('repl')
var net = require('net')
net.createServer(function (socket) {
var r = repl.start({
prompt: 'socket '+socket.remoteAddress+':'+socket.remotePort+'> '
, input: socket
, output: socket
, terminal: true
, useGlobal: false
})
r.on('exit', function () {
socket.end()
})
r.context.socket = socket
}).listen(1337)

I'm curious, too -- I'd like a remote REPL participant to be able to see the results of whatever they do, in their own REPL, instead of having that output "leak" back into the terminal where the program is running.
