Well, I've been living with CVS and the nasty file-rename hack I
described for 3-4 years now, so I guess it's *liveable* (as long as you
have direct repository access!). But it sure as heck isn't very
likeable.

That's very good news. I wasn't really clear on whether you guys
thought this was important or not.

I'm pretty sure the only reason that "CVS+nasty rename hack" is better
than "Subversion w/ current limitations" is due to the bugs you
described. As long as these bugs are shallow, fixable, and eventually
fixed, Subversion will have the edge. When Subversion recognizes rename
as an atomic operation, Subversion will kick ass.
Keep in mind, too, that I have a much better understanding of CVS, flaws
and all, than I do of Subversion. I know how to get what I want out of
CVS, and I know full well what it can't do. I really really *want*
Subversion to come along and magically do everything that CVS does, and
everything that CVS can't do, and do it all better. Unrealistic
expectations? Sure. But the more people you convince to take the
plunge, the more of this you're going to hear (at least, until
Subversion meets those high expectations).
