How can you use something that isn't built to build the same thing unless you're using a time machine? I suppose once Colony is in production, you can create a Colony clone using Colony.
It's called bootstrapping, would indeed be interesting if they used there own platform to build it, or run it in a way right now that allows them to migrate to Colony as early as possible. As long as it does not work for there needs, it's not clear why it would be good enough for anyone else.
