Class matching

Perhaps my information is out of date, but last I knew a device couldn't 
actually belong to two classes.

I was once trying to do something similar to what you're doing with the 
printers, but you don't really know whether it will end up in the first 
class or the second, other than knowing it will only be in one of them.
