Thank you, Paul, for your remarks and your advice. I am afraid,  
though, that what you propose is beyond my capability as a (somewhat  
experienced) user since it seems to require a good knowledge of  
LuaTeX and at least some programming.

I can work with the popular (La)TeX packages, not least because of  
the good documentation provided and the friendly support from the  
community. But actual programming is another thing. (I tried to read  
the LuaTeX beta 0.66.0 manual but had to admit defeat).

It looks like I have to do without customized kerning in LuaTeX and  
for my future book projects must consider (horror, horror) switching  
to a commercial DTP solution like InDesign.

Thanks once again and best regards
