Hi cork2win,
Although I do not know for sure, I would highly doubt it. My guess is that the ObiWiFi probably uses a Realtek chipset. But I would imagine that the ObiWiFi is specifically designed for interfacing ("talking") with the Obi units. If you find anything out on your own, do let us know.
However, my thoughts are that it is best to stick with the ObiWiFi unit when using it with an Obi,
