There's also a Haskell implementation (besides the Go one pointed out above). They all interoperate.

Thank you. What protocol are they using to interoperate?

[meejah]

The Haskell implementation uses the same protocol as the Python implementation. The main difference is that there are some features the Python implementation has that the Haskell implementation still lacks (most notable "Dilation").
