Do I have to install it on ALL stations in the network, or just on the intermediary nodes?

You have to install Daihinia driver on ALL stations of your Daihinia network.

It uses a tagging mechanism to ensure that:

• duplicates are discarded (in the event that two or more stations repeated the same initial packet within some station's range);
• no looping of a packet over the mesh network occurs.

Tags are added upon initial send, removed at the final destination, and used by intermediary nodes to ensure the above said.
