Oh, absolutely. Except that really does require a lot of trust up front, which is the problem with commit access to begin with - you automatically have a very clear (and *big*) difference between insiders and outsiders, and there is no "gradual" way to move from one to the other.

So yes, for practical reasons, "commit access" really is almost always an all-or-nothing thing for most centralized setups, because nothing else really works. And when it isn't, it's just a horrible horrible pain in the *ss.

What people do instead of commit access is to set up triggers to notify people about certain subsystems being modified. Which is a good idea, but it's really a totally different thing.

It actually looks like a fine book, even though I think Karl is totally off in not seeing the big difference between centralized and distributed.

I saw it at the local Borders, and considered buying it. I didn't even realize that it apparently is downloadable too.

And it talks about a lot of other things than just SCM's.
