Great. As I said, on irc, I would like to see a normal derived tree model
example, so that I have someway to assess your stuff:
http://bugzilla.gnome.org/show_bug.cgi?id=124297

Even without that, I will try to find the time to look over this properly.

For now, your thing can also be an example, so please don't use the Gtk
namespace.

Yes, it has changed in gtkmm 2.4. You don't need to worry about that yet if
you don't want to. See this list for information about cvs modules and
branches:
