Yes, but that may be complicated because completions calls a function
that will try first to complete the common part and then update the
completions. (Look what happens when you press a letter and tab
immediately). There are few ways to go around that without braking half
of the Universe. Look where I added the code for the
completion-auto-help visible and always... there is where the magic
happens.

Maybe you will find a better way to manage what you want.

For that we have fido and similes... What we are trying to improve a bit
is the default completion engine. Then the user will choose fido, ido or
something external... it is up to him.

I don't think so but I am not sure... Most of these tools stay in the
minibuffer for completions... so they don't need to switch context.
