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?
