I had a good time with Play, but I can't say that I "battle tested" it. (I work with Django in my professional life.) Tbqh, I'm wrangling with my preference for Play/Django-esque frameworks against the design ethic behind Compojure and my love for Clojure. I haven't grokked the Clojure approach to web development. For Scala, I'd say you've already suggested a pretty good template towards the end of your post. I'm less certain for my own part for how to approach Clojure. I'd strongly consider what rb2k_ is saying about performance as well. Your data processing should be decoupled from your frontend servers regardless of what you're doing.
