I have a gist about how to set up IPython in an AWS EC2 cloud machine.
Quickly sharing notebooks as gists:
$ gem install gist $ ipython  !gist --login  !gist [notebook.ipynb]
Another way of sharing is using Anaconda/Wakario.
For this, set up an account at Wakario.
Then. share links from there (you share the file and then get the link in your profile settings).
