During a standup we actually discussed something similar using a argument to the play function instead of as part of the media URI (I like the URI method better for what it's worth), but we settled on getting the basic functionality done first. I could go ahead and cook this up though.

Even if you did you could have a timer in your ARI app to discontinue it. I also fear that by adding such an option to tones we're going to progress further down the road of having different URI schemes support and implement different things. From a user perspective this could get confusing.

I actually think it is pretty common to have tones play for a period of time and then stop. I do agree, however, that (a) this could be done at the application level, and (b) having special parameters for particular URI schemes may get a bit confusing.

I'd chalk this up to "if we need it, we'll add it". It wouldn't be a breaking change to add at a later time.

> Adds a tones URI type to the playback resource. The tone can be specified by name (from indications.conf) or by a tone pattern (comma separate pitch/duration list). Tones aren't like regular sounds in that they must be canceled manually before the control can move on to the next item in the queue.

Tones are not capable of being fastforwarded, skipped into by a duration, or rewound by a small amount. Those operations unfortunately report success rather than a lack of availability right now due to how control on playbacks is defined (a playback is either completely controllable or not). I could probably add a little more granularity to that if we want it.
