First, I wonder if you read my blog post[1] that describes how
loading your custom type can now be "faked" in the glade runtime,
this makes integrating custom widget types easier, and from 
the libglade point of view, loading a custom type is really only
a matter of calling glade_register_widget() before calling
glade_xml_new() (then again, maybe this is a little more difficult
when using gtkmm for some reason ?)

That being said, we put the old hacked out "custom" widget support
in the "obsolete" group because we believe better alternatives
exist now, I'm not really planning on removing that support
for old glade files though - maybe in some distant future.

Yes you can, the codebase is protected by GPL not the xml file :)
(note ofcourse libglade is distributed under LGPL)

Cheers,
