For anybody who cares, I've just received a reply for the above  
device from WaveTel.  The cost for the device is (are you sitting  
down?): "approximately 65,000 Euros" (!!!!) and yes it will work in  
an American lab as that is what it is designed for--it is not  
designed for field use.  I guess that it's not just the little box  
that they show in the picture but an entire support system as well!!!
