Local versioning. Ideally, FreeBSD source would come into your local tree on a vendor branch. That would allow people without commit priviledges to be able to apply source code control to their local modifications, in the contexts in which it is used. > Clearly, you don't want your local mods to be spammed and this > is what requires a fair bit of work. Define two axes of major version number, and only allow automatic update along one axis. FreeBSD controls one axis, and local user changes go on the other. > Believe me, this whole thing is infinitely easy to conceptualize and > has been for at least 3 years.

Actually, it's pretty easy. Do Exactly What SCO Does With Their Packages(tm). SCO has been able to upgrade system components on a file by file basis since the mid 1980's Xenix heydays. It's no sin to plagarize documented architecture from someone else, especially when it resolves your problems at the same time.
