Multi-user support is one of the few remaining things a desktop OS can do that Android can't. The "coffee table tablet" use case would greatly benefit from a multi-user setup, as would an enterprise user who wants to keep work and home separate. It's been a top 20 item on the Android bug tracker since the debut of Honeycomb, so there is certainly demand for it.
As we've seen from my previous experiments in sticking my nose where it doesn't belong, Google likes to leave breadcrumbs in shipping products for the astute observer to find, and the multi-user situation is no different.

One of the great things about Android's ecosystem is the number of indie developers who are able to enter the market successfully, providing a great product and inspiring would-be developers to join in. For many though, Android development in general is a mysterious topic. How an app or game goes from an idea to an entry in the Play Store is unknown, but (thankfully) not unknowable.
Of course, considering how major development studios bring apps to life doesn't require too much thought – major companies like EA, Disney, or Rockstar have no problem hiring designers and developers to crank out and maintain polished apps.
