PPCGeeks - IncaX- Live video streaming/Video calling?

I ran across this software from IncaX. It claims you can stream video from PPC to PPC. I was thinking...I wonder if this could effectively be the same as making a video call?? If this can stream live video from one PPC to another, would that include sound? If so we could use this to make our Touch pros or Other PPCs with video capture into a video calling device?

Live Media GPS is a new service which allows streaming of live video either from a mobile phone to the web or the other way around, or directly from one mobile phone to another. It is cross platform and does support Windows Mobile, with the cab file downloadable directly from their website.
Uniquely it also allows GPS data and associated maps to be transferred with the video stream, allowing real time tracking which may be very useful for visualizing a cycle race or cross country trip for example.
This video shows, which shows a video stream being sent from a HTC Touch Diamond to a Samsung Omnia, demonstrates the service.
