Milliorn says he started out developing apps on his own, but the business is just too big for him to keep up so he's selling all of the apps and their rights, all of the source code, and technical support for two months to transition everything over to the new owner. He doesn't specifically say that he'll transfer the developer account on Apple's App Store to your name (he says he'll send over a DVD with the source code and transfer "the whole kit and caboodle" to you), but we presume that's what will happen -- of course if you go for it, you're doing this at your own risk.
What will a burgeoning App Store business, complete with apps like iSexyRef and Swine Flu cost you? Just a cool $100 grand. That's the starting bid in the eBay auction, which has just over a week left and no bids as of this writing. There are certainly less expensive ways to get started selling apps on the store. It only costs $100 to register in Apple's Developer Program for a year, and then you just need to find a developer you can pay -- or even do it yourself with a helper service).
If you'd rather start off with a bunch of marginal to silly 99-cent apps and happen to have an extra $100,000 lying around to spend (maybe for a nice holiday gift?), here's your opportunity.
