If the anti-Tivoising CC-BY-SA parallels the way I understand the GPL to work, 
yes you could so long as the manufacturer could not change the BY-SA file 
after manufacture either. If they had a way to, you would need a way to. If 
they actually baked it in so that it could not be changed, they would be 

Is this how we would want the anti-Tivoising CC-BY-SA to work though?
