If you look at the `PSNFSS' font sets, the expertized ones already have virtual fonts combining the two raw originals, and kerning can be done. no problem at all > The second question, which I discussed, is how supplying the information > one would normally expect from TeX's full capacity.

It _is_ true that you need extra metric information to build good math metric files for TeX, but thats another issue. Y&Y add extra detail in the AFM files for Lucida Math for this reason. Sebastian
