My Sphaera project is nice and useful when used alone, but I designed it to be expandable quite easily by adding more Raspberry Pis to the LAN
Also, with the new extremely low cost Raspberry Pi Zero You can add several expansions at an affordable price without sacrifying system performance, as this new board has the same performances of an A+ model.
In this article I will show you just one example of configuration, but adding a new Raspberry Pi would be almost the same for any number of them.
It will be a short and surely not complete description, but could give you a starting point for building something similar. Anyway if you have some question about it, just ask.
