I think this is an interesting idea.  Now here is something
interesting:  When I have implemented the various interfaces
where you use single keys to select something, I usually implemented the
customization so that people have to configure *characters*.
For some inexplicable reason, in org-agenda-custom commands it is 
strings,
so that it is actually easy to extend this.  So I tried on the
train today.  The change is not trivial, so I was wondering if you would
like to do somme beta testing before this gets out into the wild:

Assuming you will, I am attaching my development version.

What you can do here:

- Add a desscription string after the key,
   like

    (setq org-agenda-custom-commands '(("x" "My power cmd" tags-todo 
.....)))

- Use keys that are more that one character, the first characters become
   prefix characters.  Like

   (setq org-agenda-custom-commands
         '(("ha" nil tags "+HOME+Adam")
           ("hb" nil tags "+HOME+Bastien")
           ("hc" nil tags "+HOME+Carsten")))

I would be interested if this is all stimm compatible with
your previous customization (it should be) and if you indeed find it
useful.

Thanks.
