I expect 1 face with 2-sided lighting is best especially on iR

It requires less bandwidth (half that of your other option) and
your other option (2 faces with opposite normals) would also
require backface culling which is slow with the current iR software.

I'm not sure what 2 sided lighting will cost so youre still
best checking this to be on the safe side.

Rgds,
Angus.
