Nothing special. SFS2X was running. I changed the machine IP in the Unity editor inspector to the IP address of the server that SFS2X was on.. a machine still on the same subnet.
The " skybox info.txt" problem by the way was a space at the START of the file name. In the usual Standard Assets its got an underbar there.
I am working my way through tutorials and trying the example... just holler if you don't appreciate the notes and I will stop
--------------------
In the Unity5 Examples Connector.cs script around line 30.. to keep everything nice and clean, I suggest enclosing the declaration of defaultWsPort in an #if UNITY_WEBGL compile time wrapper...
#if UNITY_WEBGL
private int defaultWsPort = 8888; // Default WebSocket port
#endif
----------------------
If I do a PC Standalone build of "Connector" I see 4 errors... these may all be in C# assemblies that are not actually used in the example..

If #pragma target 3.0 is added into that code, it does then compile, but with 6 further warnings.
