Nothing prescient about that. The MAD concept was first proposed by Herzberg and Lau in 1967, much before sycnhrotrons were used for protein crystallography. Herzenberg, A. & Lau, H. S. M. (1967) Acta. Crystallogr. 22, 24-28. http://scripts.iucr.org/cgi-bin/paper?S0365110X67000040 The PNAS paper even refers to this article.
