360 on multiple devices for multiple users?

Hi all,

Just a general inquiry about norton 360 across multiple devices -- I see for $69.99 I can get norton security across 10 devices for one year. I live in a sharehouse and one of my roommates wants to split it and both put norton onto our computers. Will we run into any problems doing this? Or is there something in place so it must be used by the same user across all devices?
