Iterator adaptors

While looking at revamping STLport's iterator debugging code using 
iterator_adaptors as an example, it occurred to me that the wrapped 
type need not be an iterator at all. Given the right policies class 
and traits, you can make an iterator out of anything. It leaves me 
wondering whether we should loosen the constraints for usage, and if 
so, what exactly we're describing. Thoughts?
