I talk a little bit about the idea in software development of "eating your own dogfood" as well as the narrower idea of self-hosted systems (for example, building the version control system you use to manage the software you are building).

There are some interesting examples of how this is done in systems like IPFS (it self-hosts its front-end, for example) and some potential ways that Cacophony could leverage this capability for pluggable UI or version updates (whether they use a Cacophony channel or just an IPFS public key).
