Can nm provide connection speed ?

["thibaut bethune" <thibaut bethune gmail com>]

Some softwares requires to know what is the user connection speed to deliver the best experience.

For instance, Totem has a YouTube plugin that allows the user to browse YouTube videos. YouTube website provides different resolutions. The choice of a larger or smallest resolution depends on user connection speed. At present time, Totem allow the user to set its connection speed to get the best resolution. It could be much smarter if the system could "guess" what is the current connection speed and automatically set the best resolution (see http://bugzilla.gnome.org/show_bug.cgi?id=521536#c13 )

Is there a way to know what is the current connection speed with nm ?

I know that nm can tell if the user is connected or not ; it would be great if nm could tell how fast is the connection.

Thanks
