While I bought the product immediately, it is more to support the author to improve the product. I listen to my Sonos a lot but I don't necessarily keep my MacBook Pro on all the time. That dependency needs to go. I do hope this continues to work. Apple is quick to change protocols and kill interesting products like this.
Extremely simple to set up and appears to "just work". Hopefully Apple won't break it with changes to the AirPlay protocol down the road!
