Subversion's lack of support for merging between separate repositories means it's much better to have everything in a single, organization-wide repository, even if that means you need things like path-based authentication to enforce project boundaries. And it's best to do this preemptively because there's no good way to import project history when you discover you need to merge differences later.
At least, that's been my experience. Subversion really does encourage centralization.
