This platform has the potential to be an amazing home automation audio centerpiece. One thing lacking is the ability to have a paging input that overrides the currently playing source. An example would be door-bell, phone ringing, announcements from automation system, Alexa or OK Google output. I'd like to take the output from my Amazon Dot and send it into Audio Acacia then whenever Alexa speaks to me, I can hear it on my good speakers anywhere in the house and not on the Dot's crappy speaker.
Further, there is potential to take this further with eventual support for intercom style audio routing.
