Polytonic Greek

would be nice. Otherwise, excellent font. If you do this, might I suggest an inverted breve instead of the wavy circumflex? This is simpler and more suitable to this kind of font. (And better accomodates an underlying spiritus.) Also, it seems most monospace fonts with Greek have trouble making the difference between ἄ and ἅ sufficiently clear unless the fontsize is unreasonably large. DejaVu/Menlo is an exception.
