The intercom feature should be fairly easy for them to implement. Whether Bezos Bozos can pull it off is another story. And how well they implement it, if they do, is still another story. I think for it to work really well, you will need to be able to communicate between specific Alexa devices within the home/office rather than just blast the voice over all the devices. Otherwise you would annoy the whole household when you only want to talk with a specific person in a specific room. I doubt the intercom will work between Alexa devices on separate accounts though. So if your kids have their own account, that might be problematic unless Amazon allows multiple accounts to use the intercom system. Obviously Amazon really needs to thoroughly think this through, and that is one thing they rarely do.
