here is multi-region.el

working right out of the box.

http://www.ph.ed.ac.uk/~s0198183/multi-region.el

It comes with a command

,----
| (defun multi-region-execute-command (&optional arg cmd)
|   "Perform a command on all active multi-regions.
`----

Remains just to revert that, making it work at all
non-active parts.
