I get the impression that Clojure is at least entering the conversation in some places. Some companies that need concurrency control capabilities that they find difficult to implement in Java are starting to use Clojure, or at least considering using Clojure to make certain Java business applications threadsafe. The fact that Clojure runs on the JVM and can be called from inside a Java application makes this easy to do, but in a bottom-up campaigning situation the hard part is convincing management to sign off on your use of the language as an "approved tool."
