Neat! I've been looking around for a comprehensive guide in how to write a custom React renderer for an upcoming project of mine. It's unfortunate that Facebook hasn't had the time to document the process, often leaving folks to have to poke around at how other libraries do it. I'm starting to really appreciate how React can be used to incremental render complex state configurations to mediums other than the DOM.
OP: thanks for taking the time to write this series! It'll definitely help me out with some work I'm interested in doing.
