View release number from admin interface

It would be really convenient if I could view which version (release tag) my Drupal-based site was running from the admin interface somewhere. I manage a bunch of Drupal sites, running various versions of Drupal. They are at various hosts with varying access (some with shell, some with WebDav only, etc.), so it's even more inconvenient to retrieve the CHANGES.txt file for a site just to see which version I'm running.

I'll even be happy to code the admin interface to do this, if someone in the core group who packages the releases can commit to putting the release tag someplace consistent where Drupal can retrieve it at run time.

Note that the CVS $Id$ tags are all accessible in the files themselves, but CVS is unable to place an expanded keyword for a tag in a similar fashion (CVS's inconsistent and inadequate handling of tags is probably its biggest flaw in my view).
