It's a bit more specific than that the way I understand it.
Consider the repos to be layed out like:

 A/
   B/
     f1
   C/
     f2
   f3

Doing:

$ svn co -N <baseurl>/A

gives you:

 A/
   f3

as a working copy.

Now, enter A and do:

$ svn co B [the new feature Robert is suggesting]

This gets you:

  A/
    B/
      f1
    f3

where B is in the entries file of A and will therefor
be automatically updated with svn up in A.

It works only in working copies in my mind. Otherwise you end up creating
administrative areas in normal directories.

I'll leave the rest up to Robert then ;)
