Haven't read the all thread, but, why not having a object that have 
both an _repr_ and and _repr_html_ (supported by qtconsole) 

class Bunch(object):
    def __init__(self,value):
        self.value = value
    def _repr_javascript_(self):
        """only notebook can do
        will result in output in JS console **not in notebook itself**
        return 'console.log("'+self.value+'")'
    def _repr_html_(self):
        """qtconsole can do too"""
        return 'html:'+self.value
    def __repr__(self):
        """ the rest """
        return 'plain:'+self.value
from IPython.display import display

def displayer(string):


-> what you expect depending on the frontend.

My 2 cents.
