Could you clarify a couple of acronyms - YIGs, VXCOs?

Also isn't the real viability issue with this the MSC? Once you've registered with a base station you need to backhaul it to a switch that's capable of routing the call to another hand set. Maybe there are some good affordable options now for a soft swtich that also provides HLR/VLR capabilities? A real class 5 switch like those made by Metswtich are hundreds of thousands of dollars I believe.
