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

I think that might be possible, though it would require ipython being 
able to have "text cells" with arbitrary html, rather than just 
markdown.  The Sage notebook format looks something like:

arbitrary html

{{{
input
///
output
}}}

arbitrary html

{{{
input
///
output
}}}

arbitrary html

etc.

Of course, sage-specific things like interacts wouldn't work.  (However, 
over the summer we've written a version of interacts that is independent 
of Sage and relies instead on the new ipython messaging protocol; it's 
part of the single-cell server project: 
http://utmost.aimath.org/#august-2011.)

Thanks,

Jason
