I think we can do that with -N  (no-recurse) checkouts along with svn ls. 
I have been experimenting with that and it seems to work. So no need to 
checkout the entire branches/ or tags/ tree.

I had been expecting the need for an absolute URL with svn:externals and 
hence the need for an anonymous access to kde-common/admin. I don't think 
there's a way out, unless you ask people to ln -s kde-common/admin to 
every module.

Hmm... hold on for a minute. I've just got an idea: symlinks

$ ln -s ../kde-common/admin admin
$ svn add admin
$ svn ci admin -m "Adding admin"
Adding         admin

$ cd ..
$ rm -rf kdelibs/
 svn up kdelibs

$ ls -l kdelibs/

$ svn diff -r 30:31

Does this solve our problems?

I think losing the full functionality forever is not interesting. If it's 
just for the imported repository, I'd say it's ok. And it is preferrable 
to have several shorter downtimes, IMHO.

Now, if we take the step-by-step solution, we have to take care about 
branches being changed in both Subversion and CVS. It isn't a good idea 
to rename the branches in Subversion, then cvs2svn more data into them.

(Look at our current /branches/KDE* to see what I mean)
