And it can not be done that simple ;-(

There are some calls to Fcompleting_read (the C imlementation of 
completing-read). This makes is necessary to write a new C function 
taking care of these calls. This new function must be able to call the 
lisp function pointed to by completing-read-function.

I do not know how to do that.
