Viewing Vectrosity lines from multiple cameras

My scene contains my main camera which is looking down towards a map (topographical). I am using Vectrosity to draw 3D lines on the map surface. I also have zoom bubbles that contain their own camera and zoom in on sections of the map. If I have one line I want it to contain the same thickness for all n number of cameras at multiple level of zooms. Is this possible?

My solution right now is to create 2 lines, one is for the main camera and one is for the lenses. When the lenses are created and zoomed I call VectorLine.SetCamera(theCamera); when the lines are drawn on the map I set the camera to Camera.main.

However, this breaks down when multiple lenses are up and they are being zoomed to different levels simultaneously.
