If the intersection of Emacs and Plan 9 fans includes more than just myself, know this: I have implemented Acme-style mouse chording in Emacs: acme-mouse.el. Use it like so:
(require 'acme-mouse)
There’s no way to turn it off, unless you manually rebind all the mouse keys. Here’s the current behavior:
I’ve tried to make selections behave like Acme, and not like stock Emacs. So, pasting highlights the pasted text and delete-selection-mode and transient-mark-mode are both turned on. Selecting text does not copy it to the X11 clipboard. You’ve got to cut or copy for that.
There’s some known weirdness when clicking outside the Emacs window, and I have no idea if this works in console mode, and it’s probably doesn’t work on OS X. But Apple mice are useless anyway, so no big loss.
I realized tonight that it would be easier to move my blog to Posterous than to add spam filtering, Delicious and Twitter integration, and search. So here it is.
and what each claims to be inspired by or based on (dashed outlines indicate it's not a window manager, or not available for Linux):
