DBus signature for gtk objects

I want that for sharing Oficina (paint) activity through the mesh.
When a user enters in a shared drawing, the owner would send his pixmap for
this new user.
Maybe serializing the pixmap wouldn't be a bad idea, cause it's passed once
per user who join the activity and wouldn't let the activity slow after
loaded.
If you have any other advice, please let me know.

Thanks
