Actually, it's in own format which can be converted to BDF. Someone converted an older version to ttf: See http://software.freshmeat.net/projects/lhudesing/?topic_id=850 The people working on XFree86 have plans to convert the BDF's and PCF's that come with X to TTF fonts with one blank scalable glyph and the actual data stored in a bitmap data in the font. (It's actually a better format for the problem in many ways. Go figure.) I don't know if Microsoft Windows will like such a font, though.
