Perhaps that is what you mean when you say "shared meta-data" but that wasn't my understanding
of this.

Pristines are a subset of the meta-data, so shared metadata implies shared
pristines.

Note that you can share pristines between branches today by using a single
working copy for all branches you work on. Check out the repository root
with the "--depth empty" option and then pull in the branches you need
via "update --set-depth=infinity".
See http://svnbook.red-bean.com/en/1.7/svn.advanced.sparsedirs.html

Note that with Subversion 1.7 this will only reduce disk space, not network
traffic. Preventing Subversion from downloading the same pristine multiple
times is currently being worked on. That feature should be available in 1.8.
