Hi y-p !

Look really nice !

Did not have time to look into the source right now, but I'll definitively will. 
Do you think  the data exchanged with the kernel in some cases could be store either in the metadata of cells, 
or in the Json representation of displayed object ? 

If we do this and by carefully crafting the "js plugin"  they could be loaded by nbviewer and read sone data in the dom injected.
Which would allow a limited interactivity on nbviewer. 

Do you rely on display_javascript for the initial loading of javascript ? or inject <script> tag in a display HTML
If you do , this can be problematic in the future.

> There's a lot of experimentation going on in this space, This is my offering.
> The proposed solutions I've seen so far all seem to stray in one way or another
> from the beaten web-development track. Exhibitionist tries to do things
> as closely as possible to the way they generally work in web development.
> A short summary of the main points:
> - data is exchanged using AJAX, your python objects become API
> endpoints on an in-process web server.
> - you can exchange messages between python and javascript, in either
> direction, using websockets and a built-in PubSub implementation.
> - no quoted code.
>   that means, no "console.log('def myfunc():\nprint \"it\"'),
>   nor 's += "console.log(\"you are quoting again...\")"'
>   javascript lives in js files, python in .py, and HTML can be generated
>   with your favorite template engine.
> - Views are vanilla web application viewable in any browser, no IPython
>   dependency for use or development.
> - OTOH why wouldn't you want to use IPython-notebook's awesome inline HTML display?,
>   works just like you'd expect.
> - Repo contains serveral examples, including a heavily documented skeleton project
> - Supported Python 2.6,2.7,3.1,3.2
> - Tests, Coverage, tox, travis, yep.
> - BSD licensed
> - Currently Tested on linux only, you can help there.
> The primary example included  is a javascript grid UI for pandas Dataframes
> that loads data on-demand via AJAX. a screenshot is available from the Github
> project page.
> Exhibitionist is built as a standalone library on top of Tornado (also
> used by IPython), and it allows you to craft views either for 3rd party
> library objects, but I also Imagine it as a primary dependency of libraries
> in the pydata arena, that integrate HTML views as core functionality of
> the library, allowing all it's users to work with rich views either
> in a modern browser, or in IPython-notebook for the best UX.
> Repo lives at: https://github.com/Exhibitionist/Exhibitionist
> Please try it out, report any issues you find and provide feedback.
> I hope you find it useful.
