Heh. Yeah, been there. I used to design medical electronics for neural 
implants. All the designs had to be very belt-and-suspenders, and there 
was often a trade-off between keeping things the way they were, and 
keeping things supported or robust against the next potential threat. 
Since one of my first systems adminstration tasks was cleaning up after 
the Morris Worm, partly because I had specifically been forbidden from 
implementing the available system security patches to avoid any 
complicatons in a BSD 4.3 controlled neural stimulator, I got to see the 
booby traps of local configuration issues up close and personal.
