AFAIK it is multi-step operation (find where first tag was
copied, find where the second tag was copied, then log between
those revisions in the main directory). Not too easy (and not
too well handled by GUI tools)

Add to that the presence of gui tools. I tried RapidSvn. Having
tags directory with no more than 100 tags causes it to
recalculate something for 30 seconds every time I click tags
directorly.... Just to view what's inside...

The problem is that I want to restrict accidental tags changes,
not all!

Using CVS I frequently happen to multi-step place one tag (tag
some files, then tag some other files with the same tag). It is
also useful to sometimes deliberately change some file version
within the tag.
At the same time CVS will not allow me to accidentally commit
within the directory checked out by the tag.

I can't imagine how could I configure subversion so it reproduced
the behaviour above...

But if I don't have this authorization, I will not be able to
create the tag!
