Is the Gauddi system fully scalable through any changes in my network size and structure?

The Gauddi eco-system is designed to accommodate whatever structure you need at any given time. It has Workspaces that can each have multiple (unlimited) Sub-Workspaces. 

Every (Sub-)Workspace can have its own Network of players formed into a tree structure with Groups and Players. You can grow from having a single screen to a vast multi-screen network, without any complications.
