At least one biggie: Perforce. http://www.perforce.com if you're
interested in seeing how "properly commercial" they are.

I can tell you that does not scale well to a corporation with > 1000
software developers. Imagine code being critical pathed on a single

If you're code is such that there's only one person that can understand
and modify it in a reasonable amount of time, you've got bigger problems
than copy-modify-merge.

How could you, as the project manager, possibly allow development on the
code base without software development plans, coding style policy, and
design/requirment documents?
No version management system is a replacement for poor coding practices
and lack of software development process. It's just that certain
versioning systems hide it more than others.
