Create-only access to tags subdirectory

I'm OK with Subversion's approach of using cheap copies as tags (I
am, honest I am, no really...) but one thing I do feel somewhat
nervous over is that a "tag" is neither more nor less "frozen" than
any other copy of the project. Mistakes, misunderstandings, or even
lazy "it won't matter" shortcuts do happen, and the integrity of a
tag can be lost.

Ideally, I'd like to make the tags subdirectory of my repository
"create only" - ie, copies can be added to the tags directory, and
read, but once they have been created they cannot be updated.

I can't see any obvious way of doing this, although I have to admit I
haven't looked too closely at the security features (I don't know
much about Apache security, of which this is a subset, so there's a
lot to get to grips with :-() Can anyone give me any pointers? (Or
tell me it's impossible so I don't waste time on it!)

Thanks,
Paul.
