We have an el-cheapo Chinese lasercutter with a LAOSlaser controller 
(total cost < 2k EUR), but still the most expensive piece of equipment 
we have. So far the big signs we put up have prevented any idiocy such 
as you describe. There are still plans to use several interlocks + 
iButtons for authentication, but billing is so fare done based on pen + 
paper and time spent with the lasercutter. Is not as nice as burn time, 
OTOH setup time still occupies it.
