Multiple audio systems in different rooms; how to link them with streaming gear?

I want to go "all in" on hi-res streaming; hoping at the same time I can link multiple systems (like for a party).  Media room has Oppo 203, Lexicon MC-12, and Bryston power amps.  Family room has AV receiver and Logitech Squeezebox which plays files stored on office computer. Outdoor has Emotiva UMC-200 driving pro amps (Crown, Mackie).  Bedrooms have vintage separates (Parasound, Adcom, Sumo, etc.) playing CDs on Oppo DV-970HD's.  I'm considering Tidal or Qobuz on Roon (with Nucleus).  Will the Oppo 203 and Squeezebox work as end nodes?  What would be decent endnodes for the other systems?.  Or do I just get six Bluesound Nodes?  Max budget is ~$4k.
