Ive been using StreamToMe for a month and it works as advertised. The app on the iPhone runs without a glitch and the server app installed on my early 2009 mac mini is so unobstrusive that I can barely tell it is running and performing the streaming on the fly.
I think the app has room for improvement, and Ill email the developer with a few suggestions, but I give it five stars for the seamless mac/iPhone integration and ease of use.
