Well, my idea is that AFM2TFM be revived to where you can use it
to make TFM files complete with ligatures and kerning pairs.
As you may have noticed, I have been lobbying for a lot of things
that should happen that do *not* involve buying anything. For
example, having all TeX implementations read all three flavours
of line termination. Don't need to buy Y&Y TeX for that :-)!

How is this relevant? I thought we were talking about Type 1 fonts.
WriteTFM is not restricted to TrueType fonts -- it works for
any font format properly installed in Windows (which these days
is just three: Type 1, TrueType and OpenType).

Small changes to AFM2TFM would make it actually useable.
Namely making it able to do kerning and ligatures.

Both. It first has to create a suitable AFM file (with added comments)
and then call AFMtoTFM. How it links to AFMtoTFM (DLL or EXE) is less
significant. To create a good AFM file it has to trace out all the glyph
outlines, follow calls to construct composites from base characters etc.
and do this for the different font formats.

I disagree, I think we should (i) turn off meaningless complaints
from current versions of applications and (ii) use the radix 40 scheme
described elsewhere to hide the name of the encoding in the checksum
for advanced applications that can check this :-)
