Yup, but there are issues with that.  For one thing you can not do an 
atomic commit from the top of the tree and have it go into the sub 
project correctly.

 From here:
http://svnbook.red-bean.com/en/1.5/svn.advanced.externals.html

"The support that exists for externals definitions in Subversion remains 
less than ideal, though. ... And Subversion still truly operates only on 
nondisjoint working copies. So, for example, if you want to commit 
changes that you've made in one or more of those external working 
copies, you must run svn commit explicitly on those working 
copies—committing on the primary working copy will not recurse into any 
external ones."

Also, it would mean converting ITK, VTK, ParaView and CMake all at the 
same time....

So what we need is a way to bridge CVS to SVN until all projects have 
been moved.  And we need to figure out a way to deal with the external 
stuff in a way that works.   Basically, it is a bunch of work for us to 
move...  I am not saying we won't, but there are still details to work out.
