telnet.js

#!/usr/bin/env node
// requires node v0.3
// telnet.js 80 google.com
net = require('net');
a = process.argv.slice(2);
if (!a.length) {
  console.error("telnet.js port [ host=localhost ]");
  process.exit(1);
}
s = require('net').Stream();
s.connect.apply(s, a);
s.pipe(process.stdout);
process.openStdin().pipe(s);

That is kinda too awesome. Only what about \commands? :P

I second that. I really like how streams have evolved with pipe(). Very cool.
