We need some integration support to complete this

The initial work on Rust IPC support is now complete 🎉🥳

Congratulations [~nevi_me] and thanks for all the hard work on this!

I am working on building a flight server with DataFusion over at https://github.com/andygrove/datafusion-flight-poc/tree/master/rust but would be happy to move this into the arrow repo as an example if that makes sense.

Seems like it could be a good idea if only to keep the Arrow-Rust community "hacking together" so to speak
