All that parsing and unparsing would be expensive: you might as well deal
in binary immutable objects instead. But otherwise the idea is good and
has been in use for decades (Unix pipelines being the best-known example).
The key is to share nothing except immutable objects.
See Flow-Based Programming, a framework based on passing around immutable
packets between components (there are Java, C#, and C++ versions) at
