It's true that the shoemaker's children often go shoeless; so to my little Sourceforge project, Beyond CVS/SVN - maintained tirelessly over the years by Chris Callendar - has had to wait *years* to finally get its own update site.
Sad, I know. But thanks to a recent breakthough in being able to insert associate sites into p2 repo metadata, you can now install Beyond CVS/SVN without having to hunt down Subclipse or Subversive's update sites.
Here's the new site: http://beyondcvs.sourceforge.net/update/0.8.x. If you point Eclipse at it, you can install the features therein. If you point a browser at it, you can see instructions for how to do the install. And if you want an offline install, here's the zip: org.eclipse.externaltools-Update-0.8.9.v201003051612.zip (README).
