GSS3 and wireless network support

I'm just starting to puzzle through what is needed to add wireless networking into WinPE5 with Ghost Solution Suite 3.0.

My Google-Fu finds a few things for WinPE3 and WinPE4... so wondered before I start the trek if anyone else has made headway here?

The reason for requiring wireless network support is that we have some machines which do not have wired NICs. They have one USB port, so a USB NIC dongle is technically an option, but the environment doesn't suit deploying these.
