Unity for Kinect visualization

Though I am completely new to Unity, but it seems to be an optimal tool for tasks like:

• Workspace visualization (static model)

• Skeleton visualization (from Kinect)

• Robot visualization (from model, and real time controll data)

• Collision detection

• Alerts

Most of the data would come via network. Is there any limitation in using native C# in a Unity project?

Will the functionality level of the free version be enough for that task?
