On the hardware end of things, I'm thinking one could use 1 USB sound

If these draw power from the usb hub, you'll need to watch the total amount
of power being used.
How many USB sound cards could a single i5 ish PC running linux in
console mode feed ? (MP3, wav, flac formats)
Probably as many as your hardware will support.
Sometimes one will want to play the same music simultaneously across
multiple zones. Ie, during dinner, one might want to play music in the
kitchen and the dinning room. Is there a way to sync playback between
multiple USB sound cards ?
You should be able to get pulseaudio to play the same stream to multiple
devices. I would expect them to be relatively close to in sync. I am not
sure how to easily do this.
