I am looking at it from an ARIN justification point.  If you are a small 
operator and need a /24 you have justification if you give customer’s publics, 
but is it a great line if you are only giving out publics for people who need 
cameras or need to connect in from the outside world. If I need a /24 and I 
don’t really use it all am I being shady?  It becomes a “how much of a grey 
area is there” kind of thing.
