Not sure I fully understand, py2tex does allow to do some nice things.


And we are also working on having the ability to do 

the value of x is ::x::
in a markdown cell, 
where ::x:: will be replace by the actual repr of x in the kernel.
Still thinking on the best syntax and how to choose between tex/html/.../ repr.
