I do not understand why this is not already available. It's not like it's top secret information that will crush the company if revealed. If anything, it will help vshare because it will make it easier for people to build better sites to be showcased (rather than have a site showcase folder full of sites that all look the same). It will probably also cut down on their work load a little since it will make it easier for people to solve trivial issues themselves.

On the topic of payment processors, I am not sure since I've never played with the packages feature, but can't you just substitute the paypal api with the one for the processor you want to use? I use paypal all the time, but it's honestly my least favorite provider, and those of you running adult sites are playing a risky game.
