I'm sure i shouldnt say this, but more than once I have written 

if ( !$x == !$y ) { ... }

which I think is a fair exception to your rule. I kinda view ! and !! as "boolean constructors", and so long as both sides of your (in)equality are guaranteed to be a "boolean" obtained one of these constructors you can compare them.

But I'm really just nit-picking. :-)
