Will audio ads replace adsense?

Back in 2007 NetAudioAds Pay-Per-Play was formed. They are a company that sells and distributes audio advertising. They were founded by Charles Heflin and Larry Post. After being in beta test mode for quite some time now it seems they are about ready to go live with a vengeance. BPA ( a major auditing firm for media advertising) is almost done with the audit. Although there has been a lot of controversy surrounding the idea of audio ads being played while viewing a website there still remains the fact that this could become a viable source of advertising for businesses and an income generator for website owners. All you do as a publisher is sign up at their site, insert a small piece of code on your site and you're off. Then when someone vistits your they may hear a small 5 second advertisement. There also an option to have the user press a certain key and they will be directed to the advertiser's site in a new window. I do have the code installed on this blog (why not? I have adsense code also and no won seems to pay any mind to that). Before the audit was completed they were only running a small quantity of ads throughout the network. There has also been some naysayers as of late due to the fact that it is taking longer than expected to get the system running at full speed with as few errors as possible. Only time will tell if this will be a viable alternative to other advertising such as Google's Adsense. Please let me know you think of this concept and if you are interested in joining please visit NetAudioAds now.
