Nexus 10 multiple user accounts impact on our app/game

Apparently, Nexus 10 supports multiple user accounts …

“The Nexus 10 allows for multiple user accounts, so that a family can share the device and keep separate apps and settings for each user. It also has stereo speakers and a standard tablet battery that lasts for nine hours.”

What is the impact on our app/game or any design considerations, if any?
