Seat Licenses for packages...

Hi:

I’ve seen that some of the packages from the asset store are purchased as “seat” licenses. What is the scope for this?. I’m working with another 2 programmers and I want to assign one person to use one of this plugins. If I purchase the plugin just to have one programmer working on that specific game system, when that part is integrated to the main solution, what should I expect?, Is the solution going to crash?, will I be able to see those assets and scripts used and created by the plugin?. What is the limitation of having the license per seat on Unity Plugins?

Thanks a lot

Seat License means that all your team members need a copy of the Asset. Otherwise, something might break.
For example: If you have a GUI based on NGUI and one of your mates would open the scene in his/her Editor, nothing would work.
