Ah, I like that option. To be honest, I haven't even really tried Maple from Sage yet. To be honest, one of the reasons I want to switch to Sage for is the LaTeX export. Maple's is awful and talking to the developers, they have no interest in improving it. I've been contemplating the possibility of exporting the notebook to LaTeX, but that requires that I get more familiar with the notebook code. The code in, http://www.iwriteiam.nl/html2tex.html may be useful as a starting point. It's GPL so that's good.
