ipython notebook starts a notebook server. 
It does not make sense to have a server linked to a specific kernel. Hence the --existing not being recognized.
And i'm not sure there is short term plan to make the modification necessary to the notebook interface to be able to connect to an existing kernel to a notebook.
If I remember correctly I think that Brian is against having the ability to connect to arbitrary kernel with notebook.
