For those wondering this appears to be a new offering that sits between their enterprise offerings and app store accounts. Right now if you want to offer your internal app you need to host the IPA's, implement your own update mechanism, and get people to accept your developer deep in the Settings app. I'm guessing this lets you take advantage of Apple's update and hosting which makes sense for some apps I'm sure. One of the nicer things with enterprise is you don't need to go through app review (mainly the time savings, we can push a fix as quick as we can code it). This isn't something my company will use but it makes total sense for an internal app that doesn't need rapid release ability and saves you from a lot of management stuff you'd otherwise be on the hook for.

Now all I want is Apple to have a better story for "template apps". I know we don't want more spam in the store but getting a company to setup and maintain an Apple Dev account when they are not a tech company can be rough. I've run into this issue both professionally and for side projects. I'd gladly give Apple $100 per app and/or be unlisted if I could publish multiple builds of the same base "template app" on the same account. Maybe they will relax that restriction for unlisted apps, it still wouldn't cut it for some cases but for at least one of my side projects it would be perfect.
