Ah yes, I had forgotten about him.  The IPv16 suggestion was inspired,  
given the 4-bit width of the IP version field.

(I had guessed that John Day was referring to Paul Francis, because  
(a) Pip was nominally v8, (b) Paul was at Bellcore when he developed  
it, and (c) Pip could justifiably be viewed as an outlier among the  
"official" candidates, given its more adventurous design.)
