Exercises 19.19 :
A Cooltown user squirts the URL of a sound file or a streaming radio station to an Internet radio. Suggest a modification to the eSquirt protocol that would enable the user to control the volume from their portable device. Hint: consider what extra data the squirting device should provide answer

That is, eSquirt does not enable the interoperation paradigm with which we began this subsection, in which a client device obtains a virtual user interface for controlling the settings of a target device. For example, after squirting the URL of a sound file or a streaming radio station to an Internet radio.
