We just used adb install. It might've involved installing a special version of Android, but I deliberately forgot about that process because it sucked. Either way, I'd be kind of surprised if Play wasn't a special case, no clue what they do. (I'm no longer at Google, can't even check.)

It probably is, but there's also the
Failure [INSTALL_FAILED_ALREADY_EXISTS]
brick wall which makes perfect sense, is not especially specific to the Play Store, and will likely require root (then some careful `mv`s) to squish. Yayyy.

Much appreciated :) thanks again for the insight/feedback!
