Multiroom with UPNP Renderer

[likescookies]

Yeah, I've got a Pi running in one room with MinimServer and an old Logitech Boom in another running off Squeezebox. I'd been planning to retire the Boom once I figured out multi-room on the Pi--it didn't occur to me until like last week to check whether Volumio has a Squeezebox plug-in, which it does! So I'll likely do the same thing you are doing.
