I examined the typescript given and started to apply it. I get however a strange error in that a font is not found.
I replaced my line:
  \definefontsynonym [LucidaCalligraphy-Italic] [file:lbc.tfm]
with the given:
  \definefontsynonym [LucidaCalligraphy-Italic][name:lucidahandwritingitalic][features=default]

The font search then comes in the afm-directory, as proved by the log (in part):
fontnames | identifying tree font files with suffix afm
fontnames | error when identifying afm font /Users/hans/TeX/context/beta/tex/texmf-local/fonts/afm/yandy/lucida/lbmitex.afm: no matching pfb file
fontnames | error when identifying afm font /Users/hans/TeX/context/beta/tex/texmf-local/fonts/afm/yandy/lucida/lbmrtex.afm: no matching pfb file
...
(these being math font files)

The needed lbc.afm contains:
...
Comment UniqueID 5029013
Comment MS-WindowsName LucidaCalligraphy
Comment MacIntoshName LucidaCalligraphy
FontName LucidaCalligraphy-Italic
FullName Lucida Calligraphy Italic
FamilyName LucidaCalligraphy
Weight Normal
...

Any reason why it is not found on the font search through the [name:] scheme?

Working on typescripts for Y&Y's LucidaBright (which are type1 fonts) for MKIV (hoping to maintain compatibilty with MKII), the following code produces all math in bold, even the first x+y.

You can use mine as start, math is defined in type-otf.mkiv.
