I'm not sure I understand the details of what you're asking for
(e.g. what part of the name do you want to list as completion, and where
do you want it to be listed).

Does ido-completing-read already do what you want?  If not, why not?
The default completion code provides a `substring' completion style in
Emacs-24 (not provided in Emacs-23) and it sounds close to what you
want, but OTOH ido-completing-read also provides it, so maybe you want
some else.

Or do you want something more like what filecache.el provides?
