Maybe I'll outlive him. Anyway, Michael Price writes:

This is just a way of saying that you DEFINE "identity" by interference 
characteristics, as you have so far observed them. Sufficiency is not 
necessity, and interference is not the only phenomenon. 

Can waves of different frequency interfere with each other? Yes, although 
this is harder to observe than with waves of the same frequency. If a "red" 
photon and an "orange" photon interfere with each other, are they identical?
