This is not true.  Concurrent pricing *can* and *does* work based on 
the honesty of clients alone.  That is how real time information 
vendors price their products to the large dealing rooms.  the vendors 
are totally dependant upon the clients being honest about how many 
simultaneous users will be using the service at any one time;  they 
cannot in practice police this, but a thriving industry, based on 
mutual trust (or to be more precise, based on a reasonable lack of 
mistrust), is the result.
