How do I disable tag modification?

Hello,

I'm trying to disable the modification of tags after creation.
My tags are located in a project/tags directory as proposed in the "book".

Users should be able to create a tag but should never be able to modify
an existing tag (maybe delete a tag, that's under discussion)

I see that using a pre-commit hook is probably the way to go. In the
hook script I want to do the following:

If a subdirectory */tags/foobar is involved in the commit (svnlook
dirs-changed) and this directory already exists: abort the commit.
Otherwise: perform the commit.

Unfortunately I have not found an easy way to check if the directory
*/tags/foobar already exists. I see that in the "svnlook tree
--show-ids" output, new directories seem to have ids of the form
<4._0.t21-1> (the _0), but maybe there is a better way.

Completely different approaches which achieve my goal are of course
welcome :-)

(I'm running svn 1.1.0rc2 via apache on a Linux box)
