Full Bluesound System?

Hello,

I currently own a Vault 2 player, which I currently have setup with a Naim 5i integrated amplifier.  I am wondering if it is possible to setup a full Bluesound "system"?  I am considering a Powernode, and I see an item called "Hub".  Can all of these components be configured as one system?  Meaning using the Powernode as my amplifier, the vault2 as my player of ripped music, and the Hub to connect a CD player and turntable.  If so, would EACH of these components have to be connected via ethernet cable?  Or would the communicate to each other via another method?  Thanks in advance.
