I like the ProggyClean fonts a lot and would like to see them in my terminal. The "True Type Font" versions aren't great, but the bitmap (raster, *.fon) fonts are excellent. This should be a virtue since the Linux fonts are all raster as a matter of course.
I think the Linux font format is PSF2 (among others?) and is detailed here: http://www.win.tue.nl/~aeb/linux/kbd/font-formats-1.html.
