Per-mode obarray for M-x |

How hard would it be to make a per-mode obarray for M-x? Sort of like
the per-mode keymap and abbrev tables, I'd like to do "M-x command"
and have it act differently depending on the mode; e.g. "M-x html" in
a org-mode buffer would run org-export-as-html, but the 'default'
action in other buffers would be to run, say, htmlize-buffer.
Here's why I'd like this. There are some commands I run somewhat
often, but they have long and/or difficult to remember names. For
example auto-revert-tail-mode. I am thinking as I type "Is it
auto-revert-tail-mode or auto-tail-revert-mode?" I don't do it often
enough to take up a valuable short key binding like "C-c t", and long
key bindings can be just as difficult to remember. Even with
minibuffer completion it interrupts my workflow, so I do "(defalias
'auto-revert-tail-mode 'tail)" and it becomes just "M-x tail". That's
fine in this case, but you can see how I'm going to quickly run into
problems since there is only one namespace.
I understand this would be a huge undertaking if I wanted this to work
in general elisp code, which is why prefixes are used in function
names to create namespaces. But I just want it to work with M-x.
I am willing to dig around and make a patch myself, but I'd like
someone familiar with the internals to (a) tell me if it's extremely
difficult and/or a bad idea, and if not (b) point me in the right
direction.
Regards,
Scott
