I doubt you want to do that.
I wont do that. Thanks a lot.

'stack' is not a copy. So if your condition
is not true, TraversalRequestNameStack is screwed up.
...
if len(stack) and stack[0] == 'dview':
        # stop looking for next obj to publish by emptying stack
        req['TraversalRequestNameStack'] = []
        req['YSURLARGS'] = stack[:]
Something like that should be better:
def __before_publishing_traverse__(self, obj, req):
         """
         """
         stack = req['TraversalRequestNameStack']
         if stack and stack[-1] == 'dview':
             # stop looking for next obj to publish by emptying stack
             stack.reverse()
             req['TraversalRequestNameStack'] = []
             req['YSURLARGS'] = stack[:]
BTW: Why can't you simply use traverse_subpath?
Never heard of it :)
