That is an interesting way of distributing betas. But, wouldn't this cause more harm (bad press) than good? I never really found the distribution of betas that hard (from a tester point-of-view). You don't even have to use that ad hoc app. I tested one beta and all I had to do was load both the beta app and the mobileprovision file onto my iPhone. As a tester, it was very easy from my side. Maybe it is a lot harder from the developer end, idk.
