Working with type systems and communications can be very difficult. In Haskell, messages between threads are usually conveyed through channels that only accept a single type, and as a result are not very versatile. In networked systems, a stream of bytes is sent that hopefully conforms to one of many protocols including TCP, UDP, and HTTP, and hopefully both parties agree on what is sent and when. Session Types are a way to bridge the gap between these systems, as they can capture complicated protocols, and be properly type checked.
