Raspberry Pi in Lightweight Grid

I have 2 RPi's at the moment and I'm trying to combine them. I have launched 2 remote kernels, but I can't parallelize them. I think Lightweight Grid should help, but this library can't be connected on Wolfram Language. What am I doing wrong? This tutorial doesn't work for me
(Raspberry Pi 1) In[16]:= Needs["LightweightGridClient`"]

During evaluation of (Raspberry Pi 1) In[16]:= Get::noopen: Cannot open LightweightGridClient`.
During evaluation of (Raspberry Pi 1) In[16]:= Needs::nocont: Context LightweightGridClient` was not created when Needs was evaluated.
(Raspberry Pi 1) Out[16]= $Failed

And is there any other ways to combine remote kernels?

I added an example on how you can connect two Wolfram Language engines over a network connection:

Let me know if that works for you.

Once that works, it's relatively straightforward to extend this method to more than two Raspberry Pi's.

Himura-San, your question is indeed very interesting.
I saw the following posting in google plus.
I would appreciate comments from WRI if the following type of configuration could be leveraged.

Raspberry Pi 64-Node Supercomputer with LEGO

A team of engineers from University of Southampton have made this incredible 64-node supercomputer with Raspberry Pis and LEGO. The video above shows how they did it and you can access the full tutorial here.Computational Engineers at the University of Southampton have built a supercomputer from 64 Raspberry Pi computers and Lego.
The team, led by Professor Simon Cox, consisted of Richard Boardman, Andy Everett, Steven Johnston, Gereon Kaiping, Neil O’Brien, Mark Scott and Oz Parchment, along with Professor Cox’s son James Cox (aged 6) who provided specialist support on Lego and system testing.
Professor Cox comments: “As soon as we were able to source sufficient Raspberry Pi computers we wanted to see if it was possible to link them together into a supercomputer. We installed and built all of the necessary software on the Pi starting from a standard Debian Wheezy system image and we have published a guide so you can build your own supercomputer.”

Have you tried watching videos in:

gridMathematica channel

especially this one:

Using the Wolfram Lightweight Grid System

So does it mean that I have no any ability to parellelize remote kernels until I buy gridMathematica?
