My version:

var request = require('superagent');
var rangeStream = require('range-stream');
var gcloud = require('gcloud')({
  projectId: 'nth-circlet-705',
  keyFilename: '/Users/stephen/dev/keyfile.json'
});
var file = gcloud.storage().bucket('stephen-has-a-new-bucket-yay').file('blah.jpg');

var INTERVAL = 4000;

function gcloudRangeRequest (start, end) {
  file
    .createReadStream()
    .pipe(rangeStream(start, end))
    .on('data', function() {})
    .on('end', function () {
      console.log('done')
    });
}

function rangeRequest (start, end) {
  request
    .get('http://yahoo.com')
    .set('Range:', 'bytes=' + start + '-' + end)
    .set('Accept', '*/*')
    .set ('Cache-Control:','no-cache')
    .end(function(error, res){

    });
}
