Here an interesting question arise, in the philosophy/VCS field. We see that Linux/git adopted model where "dictator" has, say, 17 lieutenant for key subsystems, and pulls changes from them, each of them have, say, 17 own subordinates from whose he pulls, and so on. Instead of that 17^2 people FreeBSD has the same 289 men directly commiting to repository. It is repository here which acts as a "dictator" from technical side, and that is definetely better (e.g. no "kill -SIGBUS Linus" factors). The difference is, those 289 key people in Linux *can* pull changes from lower tiers, but FreeBSD people - can't (of course not at all, but it is significantly harder to contribute here). It is a plain model.
