HH...Think about it. 

What if you had a technology that could be used in thousands of business across the country and one day you got a call from someone in another country that wanted to use your technology.  Would you say "no thanks, i've hardly scratched the surface in my own country" ?  And that's not to say that WEE happened to get a call one day... no... I believe they were actively searching for customers and since they've got a global patent... why not take advantage of it.  There's really much more to it than that... but to keep it simple....
