There is a thread from a bit over two years ago which states that floating licenses are in the works.
As someone who has to manage 60 licenses I am very eager for a floating license solution. Our students would also enjoy the increased flexibility of being able to use ZBrush during the times that other classes are using the labs where ZBrush is currently installed.
Are floating licenses still on the table? If so, might we see them in one of the upcoming releases?
Thanks for your time,
