Please take time to read and share the following article about how the Rotobot OpenFX Plugin for Foundry Nuke (and others) is intended to be used in its current incarnation.
It is taken from the point of view of a visual effect process where there are multiple people in an upstream department completing the work of creating rotoscoped footage and people waiting on the work to an intermediate standard until the downstream department can start this work. Rotobot can make this wait time from days into minutes, using a few licenses and ordinary CPU based render farm resource.
