By popular demand, my custom LaTeX styles are now available for download. (All of them have been dedicated to the public domain, I disclaim all copyright.)
There are four for now, but the set will grow. The first lets you use OpenType fonts (which is pretty much any system font); the limitation is that this works only with a single distribution, XeTeX, available only for Mac OS X, and a new experimental build for Linux. A second style typesets all chapter titles, sections, subsections and subsections in a sans-serif font (instead of the default serif). Very effective when used in conjunction with the OpenType style.
The final two adjust margins to require less paper for draft prints and such. Be good, be green.
