You need to buy a Node.
Probably best to contact Bluesound directly. Yes, they do pick up the phone.
I only have Nodes, and no Vault, so I can't say exactly. But, at worst you would need 2 Nodes. Even the original Node (not 2 or 2i) will network with the Vault.-So, you don't have to spend a lot as they are available on Ebay at significant discounts. All they need is upgraded firmware.
