I work with the author, the languages included came down purely to expertise available. Additional implementations have been submitted for Rust, Haskell and Ruby's event machine. A host of pull requests have been submitted to tweak the existing implementations as well. It would be awesome to see implementations in python, c# and java. There are a number of ways to do each, I assume.
