Here's a patch containing some code I wrote to support running multiple simultaneous SLIME connections to different Lisp implementations. I think I made about as good use of the existing infrastructure as I could but may have missed something. (Speaking of which, is there a reason certain buffer local vars (e.g. slime-connection-number) aren't defined with slime-def-connection-var?)

Anyway, here it is:
