AFAIK the later is the "official" way to redistribute custom JS/CSS.
 Personally, I prefer to include the JS in the same directory is my
notebooks, I think it's easier for the user that way.  It's kind of a hack,
but you can see how I do it in https://github.com/jdfreder/ipython-d3 .
 The idea is to include a .py and .js file next to the notebook.  The .py
file has a function that pushes the .js to the page using the display
framework.  For the user, this means all they have to do is create a
notebook in the same directory and do something like `import custompython;

We don't have a nice way to package IPython notebook extensions yet...
