I played around with this last night and this morning with a laptop and a PC connected to a home theater system, and it worked excellently. You will be getting my 10 bucks shortly! The only glitch I ran into was that Web surfing on the laptop while sending audio caused occasional stutter in the audio. But simply increasing the buffer settings in AB resolved that.
Now to the point of my original question: I guess I was unclear. AB is able to nicely send audio from one sending PC to another receiving PC without any issue "one-to-one" (ie: any one sender to any one receiver.) My question is, can one sending PC "broadcast" to multiple receiving PCs at the same time providing music, say, throughout the house on multiple PCs?
I speculate that in this version, the answer is a definite "No" but at this point, that's OK, because this simple product completely resolves some issues I have had with our home theater setup. I can now simply and conveniently use my laptop to select and play music through my home theater--something that was not as simple prior to this program..
