It's definitely a possibility to design some form of RPC mechanism and have multiple parts of your application run as essentially a distributed system. There would still be the problem that the "main" application part is expecting the rest of the system to behave in a certain way and if it is maintaining state, the state to be in a certain form. So I'm not sure that you would really win much.

Also, part of the idea is to make hot-reload as little additional burden as possible. Proper compiler support would be the real solution to that but in the form presented in the article you can at least quickly switch between an efficient static build and a dev version, something that would be hard to achieve with an RPC mechanism.
