There is fairly well working Java rendering engine for LaTex formulas:
https://github.com/opencollab/jlatexmath
Supporting it would mean that we need a cell type that can behave both as input and output (sort of like the HTML cells with a "source" view mode). The way this would work behaviour-wise would be: when the cell currently has editing focus, one sees the LaTex source code. But when the cursor moves away out of the cell, the engine is called to render the formula in place.
