I've used Mathematica 5 on Linux, it worked ok for me... Also,
Mathematica notebooks can be written and stored in a notebook markup
language (NotebookML - it's XML) instead of the standard .nb files.
About decoupling input and output: You can write Mathematica code such
that it will not output cells to the current notebook, but will
instead write to a different one that you specify. In this way, you
could separate input from output.

Personally, I want better output options for XHTML+MathML+SVG...
