I had a play with this in the week and it really is an improvement over Kinsky. For those with multi-zone systems the volume control is an absolute hit ... it's simple, has a universal option or room per room from the same screen.
As suspected Kazoo works closely and offers better funtionality when used with Songbox (LINN's free media server program) but you can still use it with popular media programs like Asset or Twonky. The whole experience offers added functionality, user-friendliness and is simply more 'SIMPLE'.
Here are a couple of screen shots of the latest version I used.
