I will try to run a org-mode to ipynb converter, so thanks to your suggestion! I just wish there was an Emacs version that wasn't to differnt from everything else so other people could look past the stigma of Emacs. So thank you for the feature run down, and to be cyrstal clear I want more options, but I will only be able to run org-mode/babel myself. Requiring Emacs is just too big of an hurdle for anything bigger than a two man team.
It hurts to hear stigma and Emacs together in a sentence but I guess you are referring to the arcane keybindings of Emacs. In that case I use native keybindings for editing in Emacs i.e. the old Cntrl-C, Cntrl-V, Cntrl-A, Cntrl-Z, Cntrl-S and vim keybindings for executing commands i.e. for things like running code. This is a great setup for beginners so do contact me if you need Emacs to be used with native keybindings :)
Just to give an example of what can be done using org-mode, this is the project I am using to grok Literate Programming -- http://ray_tracer.surge.sh/
