mozembed widget

Hi,
     This is about GTK widgets to embed Gecko/Mozilla.

The mozilla tree provides gtkmozembed. This has very limited functionality.

Galeon subclasses gtkmozembed and adds lots of functionality, but that 
widget is licensed under GPL.

I haven't looked at epiphany yet, nor am I aware of much of the motives 
behind it.

Does it use the same mozembed widget as Galeon?

If so, since the set of functionalities in gtkmozembed is somewhat 
arbitrary, did anyone ever consider integrating the code into 
gtkmozembed in the mozilla tree? If so, what were the hurdles? Only that 
  they wanted a more restrictive license? Or, is it possible to have the 
widget released under LGPL?

If not, can the epiphany mozembed widget be released under LGPL?

Thanks a lot,
Philippe
