Pretty sure this is not a great idea.
However, one thing I'd like to see is a quality group of beta testers for apps that can give good consistent feedback on new versions. Currently I have a few friends/family in my beta network, but getting feedback from them is like pulling teeth b/c ad hoc installation is so stupidly cumbersome.
If someone could create a network of willing beta testers that want to test certain categories of apps, that would be a winner.
