I was hoping that by now we would have an up and coming DVCS replacement that functioned as a "github in a box" (pretty sure fossil has been described as that, but it's too much on the cathedral side). Being able to mirror an entire project though version control would significantly help with mirroring if we go back to a decentralized world. Maybe going back to decentralized project hosting is just another pendulum swing similar to how compute moved to the cloud...
