The iplot function produces an HTML representation of a plotly plot for usage in the IPython notebook. IPython also supports converting notebooks to LaTeX/PDF documents through IPython.nbconvert. To get this to work, iplot would have to also display a static image format of the plot. It would be as simply as a call to display(Image(raw_image_data)) to include that in the notebook.
We (IPython dev team) is super excited about plotly and are more than willing to answer questions, etc. about the IPython integration.
