Clarification: The article I saw about ferretlegging was most definitely not
from the 1980s, like the article that BIG cited at the end of my last post.
The article I read was current at the time my colleague gave it to me, and
that was two to three years ago -- around 1993.
 
[Moderator's note: Probably a similar article.. I'll post reference when
if get to the proper stack of paper :-)  BIG]
