How much this matters with all the little nodes from 4 speakers in play
I'm not sure.

indeed, but 50us is back *in* phase again so its never clear cut anyway
;-)

Ah, but 50us is then 180 out of phase for a 10Hz tone! I think we'd just
have to accept that the speakers would be out of phase.

certainly 'OK' for a cheap solution though.

I'm pretty sure you're right. Remember though that the speakers would
still need to be plugged in, so in many cases it'd be no easier than
normally wired stuff. IIRC, it's possible to send digital information
through mains wiring - might be a viable non-wireless solution?

Btw, I take issue with your I hate java section best to keep it OT
though.
