I don't believe they will get interactivity on the YouTube site. They take their YouTube video, add interactivity, and it can be viewed on nfusz's site, but they still get credit as if the video being was viewed on YouTube when people watch on nfusz's site. The last part is the critical piece because that is how they make money, now they can send links that are interactive and still get YouTube credit. I could be wrong, but that is what I thought was the plan.

BTW, I've seen some of D2RMarketing videos on the nfusz site, they have added interactivity, here is one I could find.
