It would be nice if all spotify premium users on the local network could use spotify connect to stream to a client (i.e pc connected to the speakers)
Now you can stream to the client only if you are logged in with the same account on the other devices. This is not that practical since there are usually more than one spotify user/account in the same household. Especially with the new spotify family being released.

Thank you for your feedback.
At this time we do not have any plans to do this. If anything changes we'll come back here and post an update.
