The lack of hinting makes the font looks ugly in small point sizes, and difficult to read. Since FontForge already includes autohinting, why not put it in good use? Beside, the hinting patent is already expired in the US. Maybe it could try hinting Latin, Greek, Cyrillic and Kana characters first, before moving towards ideographs. The ideographs 'hinting' can be done using embedded bitmaps if it is too much work. The M+ bitmap fonts are perfect for the job until proper hinting is available.

If hinting is to be done, do not try to optimize for subpixel geometry like Segoe did. Many new monitors do not arrange their colour subpixels in linear formation, so all the work will not be beneficial to these end users. And for that matter, the monitors may not even have 3-colour space (eg: Sharp Quattron). Just optimize at the pixel level.
