What a disappointment. ;--(.  I assumed you meant Keith Taylor had  
tested it with gum, and raced over there to see what he had to say,  
but it's palladium he reports on.

But I agree about the potential, whether for gum or no I can't say,  
but  I applaud the intellect that produced it and the generosity that  
offered it freely to the world.

I just saw that just now, and will try it tomorrow.  Thanks,
