Hey Alice, as one who gets tipped on the street for his musical endeavors, I find it interesting to see this development on line. There are many things that are free on the web, as a matter of fact I receive my internet access through a group called Freei for free. I would have never guessed that this could be possible but in this day and age it seems almost anything is. So we now have the capability to be virtual buskers or maybe closer to a jukebox. I kind of like that idea. The technical aspects of what makes this possible are intriguing but as one who has little knowledge of such matters I would be suspect of them. It boggles the mind. What will they think of next?
