Have I really said `useless'? This is too harsh :-) It's usage is
`very limited', this is probably a better phrase.

Probably the best solution is to load the Wadalab font into FontForge,
then squeezing the katakana glyphs horizontally and adding them to the
font... However, the results are too thin, I fear.

I think it makes more sense to use a font editor like FontForge (which
I highly recommend) to inspect the glyphs.

I'm not aware of other free Japanese fonts which really fit to the
extremely thin look of the Wadalab fonts.

What do you mean with `font manipulation'? Except doing poor-man's
emboldening by printing glyphs thrice with slight offsets, no font
manipulation can be done directly in LaTeX. It might be possible to
do some squeezing on the PS or PDF level to convert full-width
Katakana to half-width forms. Hmmm. Whether this gives good results,
I don't know yet.

I won't incorporate them into the CJK package. Instead, I suggest
that you create proper RPM bundles which could be then included
directly into a GNU/Linux distribution like SuSE. Perhaps it makes
sense to contact Mike Fabian from SuSE who has done something similar
already, IIRC, using scripts which can do this automatically.

Yes, provided the font is correctly set up for LaTeX.
