How to install a second instance of Twonky Server on WD MyBook Live for Private Streaming

I have seen the topic come a few times on how to password protect a folder
so that parents can shield their children from inappropriate media

While Twonky Server does not have the ability at this point in time
to password protect or to limit folders or media items on a per client basis
it does have the ability to limit streaming as a whole on a per client basis

We can leverage this ability by running a second instance of Twonky Server
for the sole purpose of streaming restricted media on a per client basis
The primary instance will still run as normal for unrestricted media streaming

The following example is going to show you how to install a second instance
that is password protected from http access
and is configured for a Private folder share
and is configured on a per client basis
