Well, looks like I learned a bit here...  This is all very reminiscent of 
PC software copy protection -- folks would break a copy protection scheme 
-- vendors would produce a new one -- repeat...  Now, it's hard to find 
copy protected disks (vendors gave up and went to license managers -- how 
long will they last?).  The point is: when do we give in and just move to 
a different paradigm?
