Perhaps you are right, but I was using that as an example.  I actually 
see great value in being able to declare a specific method inside a 
calls of a component/namespace as namespace-protected.  Alot of times 
you see that objects within a given component might do something like:

class Foo_Bar
{
     protected $_someProperty = null;
     public function _setSomeProperty($value)
     {
         $this->_someProperty = $value
     }
}

as a means to describe that an object of type Foo_Baz can interact with 
Foo_Bar, but Foo_Bar::_setSomeProperty() should not be considered a safe 
method to be called by a developer from an API standpoint.

Wouldn't that be nice?

Wouldn't it work the same way as protected methods work?  Essentially, 
protected methods ensure that the caller is in the inheritance (is_a) 
chain.  This would simple add a new check (for methods marked 
nsprotected) to check to ensure that the caller is a derivative of a 
specific namespace.
