Some time ago I've started a communication library based on libgobject and I 
feeled the need of two things: a base object with floating reference and a 
container. After some time, I started an experimental cairo canvas and I had 
the same needs. In both cases, no gtk dependency was requested.

Briefly, I'm not talking about a container that cover all needs and tastes but 
instead about "moving the GtkContainer logic and complexity" from gtk to 
gobject, something similar to what was done for GtkObject and its floating 

I wrote gcontainer with this in mind (the GContainerable interface is 
"compatible" with GtkContainer and GChildable with GtkWidget). Anyway, my 
solution presents some serious problems: I'm misusing the interface to hide 
as much technical details as possible to the implementing objects.

I know it is a huge task but consider this as an idea or a looooong term 
project: I don't think to be the only one with these needs.

Of course I'll be glad to have a link in the gobject documentation. Thank you 
for your availability.
