Now that connect is becoming available it would be nice to be able to connect to multiple outputs at the same time. For example I have 2 connect compatable speakers... it'd be great to have these in different parts of my house and be able to stream the same music to both.
I would suggest a maximum of 3 devices at the same time. This will allow for most scenarios to be catered for without streatching the bandwidth too much that it will degrade quality.
