You could compile coffeescript in development and commit the resulting JS file. Automatically recompiled Coffeescript is fantastic in development, but IMO, there's really no compelling reason to be compiling it production-side.
You could look at using something like a Git pre-commit hook to do that pretty trivially. I personally use a rake task that compiles all my Sass and Coffeescript to their respective CSS and JS files, then packs it into minified-and-gzipped files with jammit, then commit the resulting bundle. I end up serving pre-baked-and-concatenated assets and it works just fine.
