GL Lines not supported in Flash?

I am trying to use GL.LINES in Unity and am exporting to flash. It seems GL triangle strips can render no problem but lines do not? Is there an alternative way to render them?

Unity 4 is not an option for me at the moment. Turns out line rendering is not supported by Flash due to lack of implementation in Stage3D. With this in mind, I highly doubt Meshtopology.Lines works either. The only solution was to implement my own system that rendered intersecting triangle strips. I used a little bit of math to scale the lines according to maintain constant size regardless of depth from the camera
