Here's a more complete list of externals (trunk only, /svn only -
ignoring /svn-archive), with some comment.

cowbell/trunk/musicbrainz-sharp
    MusicBrainz svn://svn.gnome.org/svn/banshee/trunk/musicbrainz-sharp/src/MusicBrainz/MusicBrainz/

 Needs to be sorted out between the banshee and cowbell maintainers, 
 I don't know the situation. git submodules have to reference an
 entire module - you can't have a subtree - so going with a git submodule
 would require splitting musicbrainz-sharp out of banshee.

gnome-control-center/trunk
    libslab http://svn.gnome.org/svn/gnome-main-menu/trunk/libslab/

 I don't know the overall situation here. Is libslab used externally?
 If it needs to be kept like this, could be done as a git submodule;
 would need jhbuild support for submodules, since you have to
 git submodule update --init after cloning, and git submodule update
 after updating. (pretty simple)

gnome-pilot/trunk
    macros http://svn.gnome.org/svn/gnome-common/trunk/macros/

  Port to gnome-common; macros module is obsolete.

gnome-utils/trunk 
    gfloppy http://svn.gnome.org/svn/gfloppy/trunk

  Just merge in a a subdirectory of gnome-utils?

gnomeweb-plone/trunk/wgo.buildout-dev/src
     wgo.theme https://svn.gnome.org/svn/gnomeweb-plone/trunk/wgo.theme 

  Think this is dead. If someone revives the plone effort, they can figure 
  it out then.

gtkmm/trunk/docs/reference/images
    stock http://svn.gnome.org/svn/gtk+/trunk/gtk/stock-icons/
  
  It's possible to write a simple binary to dump out PNG files for all
  the GTK+ stock icons. (themed or unthemed.) That would avoid the 
  cross-reference, though would make gtkmm hard to cross-compile with
  docs. I don't have many other ideas.
