</div>(answering the Sage question here...) What do you mean when you say<br>
"share some simple mpi programs"? Do you mean running the mpi programs<br>
from the command line, or sharing the C code files, or using mpi4py to<br>
run the programs? If you can do it in python or on the command line,<br>
you can likely do it in Sage. Feel free to email the sage-support list;<br>
I'm sure we can help you there.<br>

</div>I think that might be possible, though it would require ipython being<br>
able to have "text cells" with arbitrary html, rather than just<br>
markdown. The Sage notebook format looks something like:<br></blockquote><div><br></div><div>since (almost) arbitrary html is valid markdown, I don't expect a problem there. The first notebook draft had html text cells, but we never found any HTML we wanted to use that didn't work as-is in markdown, so we disabled it to prevent unnecessary clutter. If there are real HTML use cases for which the markdown transforms html inappropriately, we can easily turn it back on.</div>

etc.<br></blockquote><div><br></div><div>That seems simple enough, though after playing with a few sage worksheets, it looks like if you make an HTML cell, it is indistinguishable from a code cell in the exported file. Presumably, IPython would only want the Python/Sage cells as code cells, whereas all the latex, text, and html cells should come out as text. If Sage doesn't distinguish between these in the file-format, then I'm not sure what we should do. Detecting the language based purely on content will certainly not be acceptable.</div>
<div><br></div><div>But the fact that Sage can have HTML that is part of a cell, as well as HTML that is *not* part of a cell makes it clear that a roundtrip will not result in an identical notebook. It may have the same content, but it will have changed structure at least partly. This is what we mean when we talk about lacking roundtrip support - not that you can't import to/export from a format, but that doing so is not guaranteed to preserve the entire document structure.</div>

Of course, sage-specific things like interacts wouldn't work. (However,<br>
over the summer we've written a version of interacts that is independent<br>
of Sage and relies instead on the new ipython messaging protocol; it's<br>
part of the single-cell server project:<br>
