Transparent Netflix only region unblock with Asuswrt Merlin

Ad-free time!, UnoTelly etc. services provide a nice way to unblock regions for Netflix and others using their custom DNS servers.

But I don't want to direct all my DNS traffic to them and I'm too lazy to manually configure all my devices (phones, tablets, media center boxes etc.). So here's how to transparently unblock Netflix for all your devices using the [Asuswrt Merlin][merlin] firmware. It's a custom router firmware which can be used on the Asus RT-N66U router for example.

Prerequisites

Enable JFFS partition and SSH login from http://<ROUTER-IP>/Advanced_System_Content.asp

netconstructor

# First, enable SSH in the Administration->System tab.
# Then log in to the device.

# Verify that https_crt_save is off
admin@RT-N66U:/tmp/home/root# nvram get https_crt_save
0

# Enable https_crt_save and verify that it was set correctly
admin@RT-N66U:/tmp/home/root# nvram set https_crt_save=1
admin@RT-N66U:/tmp/home/root# nvram get https_crt_save

Abstract

The purpose of this sample is to show the power of EventEmitter2 in the context of a specific example centered around [DIRT][0] (Data-Intensive Realtime) and [ETL][0] (Extract, Transform, Load) applications in node.js. Given the clear limitations of the V8 heap-size doing any exceptionally large data processing in node will require such patterns, and it is in the interest of the community that we start solidifying them.

Scenario

Lets suppose that you have an ETL that you need to run on a large set of logs which has already been partitioned into files of a size that will by themselves not overload the V8 heap. These kind of size-limited log or data files are common and should need no explaination.

This ETL runs with initial conditions (very common), and thus there may be many sets of worker processes analyzing the same data for different purposes. As an intelligent developer knowning the blocking nature of in-memory data manipulation you decided
