Emacs Moves to Bazaar

Noticed at Solidot that Emacs has moved their version control to Bazaar, a version control system that can work in traditional centralized way or a brand new distributed way. After going over Bazaar's users guide, I feel that the distributed way is suitable for developers all over the world and working on the same project, because each developer submit code into his local repository (the reason that Bazaar is called distributed) to record his own work, and publish his work via email and SFTP. It is then becomes the responsibility of the maintainer of the main repository to merge individual's work back into the main branch. I may need to read more about this, but anyway, it is interesting.
