I'm personally looking into iPython - it seems like a useful tool for interactive presentations.

Shiny is pretty nice for presentations and Plotly works with R. Not to knock IPyNb because I love it too.

Interestingly, Microsoft recently invested in IPython development: http://ipython.org/microsoft-donation-2013.html
