That's cool. Never would've occurred to me to try that!

Well, the issue is that, up until now, they've just been copying &
renaming the files, and ftp'ing them from the test environment to
production whenever they felt ready to "release". Most of our changes
are maintenance fixes or small feature additions, so this works decently
well--but there are some times where we've got a major project forcing
its way through the pipeline, and things get a bit uglier. Naturally,
I'm of the opinion that, if they get used to using subversion for the
small stuff, then the big stuff won't require them to change how they
work--but I need to convince them of that before the next big project!
:-)

So, to effectively "mimic" the current system, I think I'd need a
client-side wrapper script instead of a hook, which would basically:

copy new file;
svn revert new file to old file;
move old file;
tell svn to ignore old file;
move new file back;
and finally, commit.

Which is, of course, doable...I'll give it some thought, and maybe
bounce it off of one of my more reluctant co-workers.

Thanks,
-David
