JVM Tunneling

I've blogged on this idea in the past, but didn't have a term for the thought.

Define JVM Tunneling to be the phenomenon where certain languages, by running on the JVM, encounter ultra-low resistance as a proposed addition to a project or organization. The most successful JVM tunnelers are languages that compile to bytecodes and whose installations require the addition of a single jar to the classpath.

Primary examples are Groovy and JRuby.
