How about putting them into a namespace and not export it (that might  
be what Jim is thinking of). There is also the little thing that the  
chip dimensions are also stored in the AffyBatch objects so now they  
will be stored twice... this opens up some consistency things. But  
then again, that will likely not be a problem.
