No, I don't suggest that you tagg each change, I merely pointed out
that since each change results in a new revision that is global anyone
working in that repository will be able to refere to a specific change
by it's revision number without anyone needing to do any tagging.
In cvs this was not possible, you had to tag if you wanted to refer
to a specific point in time of the repo (well, unless you knew the time...).
Sorry for explaining so bad.

That depends on the demands on the external component. If you are
satisfied with incorporating new versions at a fairly slow rate then
I think you should handle it as a third party library. There was someone
who posted a pattern for that but I can't seem to find it. You might want
to search for it in the mail archives and look at this for the
functionallity:
http://www.cvshome.org/docs/manual/cvs-1.11.14/cvs_13.html#SEC104.

Otherwise if this library, if I may call it so, changes a lot you should
consider using svn:externals to incorporate it into your existing projects
as you see fit. Svn book reference:
http://svnbook.red-bean.com/svnbook/ch07s03.html.

You really should read it, it's an amazing piece of litterature :)
It's really that easy, as long as you are only using one repo you
would issue a few 'svn move' and you are done. svn book reference:
http://svnbook.red-bean.com/svnbook/re18.html

Also as far as I understand since there is no filesystem repo these
commands are not consuming loads of disk, they won't make your repo
slower and they are lightning-speed fast to issue.
