Ok, so I visited the site, and here some questions/comments:
1. I misunderstood, I thought it was a video like those you find on YouTube, but it's a 5-sec audio ad, which is not as bad, I guess, but could still be annoying, and a site visitor may avoid coming back to your site. Also, could you imagine... a lot of people do unrelated web surfing at work, and if their audio starts to play, boy would they be in trouble?
2. There is no mention of how much you would get paid per ad, is it 1 cent, or is it per 1000 plays?
3. PPP is a multi-tier program, so you probably posted your affiliate link, which is against forum rules, but would also make one wonder if you posted this to really ask the opinion of Website Babble, or so that you would get sign-ups through you. Anyway, still an interesting idea to advertise.
