It's more than an open border between the two states, since there are Swiss guards patrolling the Austrian-Lichtenstien border.  I'm not suggesting there is no political border between the two states, just that there is no border control here.  Switzerland's border control encompasses both Switzerland and Lichtenstein.  That being said, this point isn't important to the current debate, so there's not any point agonizing over it. :As for CFA versus CI/Niue status, perhaps I shouldn't have been so definitive.  But the point stands.  There are many types of dependencies, and none are the same.
