Interesting.
For what it's worth, I plan to give Emacs another go pretty soon here, but I'll be sticking with Common Lisp. I'm kind of done my courting period with Clojure.
Emacs + Slime for CL should be a piece of cake as long as you don't insist on using your distribution's packages. Mail me (see profile) when you run into any problems and I'll help you out.
