The fact that @terhechte's Ebou client (https://github.com/terhechte/Ebou) and @0x0's Kitsune server (https://github.com/kitsune-soc/kitsune) are both #Rust seems like an opportunity to get them both working closer together in ways that other projects may have a harder time doing. I say this as someone who knows nothing about Rust so this may be a completely wrong assumption.
