Applications such as Fennec would like to be intelligent about how they use their user's data plans.  For instance, choosing to download application updates when the user is connected by wifi versus cellular.  Exposing a method to js to determine the type of connection would allow this behavior.

There's a DAP draft for this (http://dev.w3.org/2009/dap/netinfo/Overview.html).

I guess we'll also want it to be exposed to chrome?

I do not think having 'connection.CELL_3G' makes any sense at all.  f/e, i sit under the worse wifi hotspot in Mountain View.  My phone would report that I have a "wifi" connection because that is the transport I am connecting over.  However, if I switch over to 3g, I get higher throughput and less latency.

Instead, we should have "some" way to tell the user what the average latency and average throughput has been over some period of time.

Getting QoS metrics is fine, but getting the connection type is still a valid feature.

We probably also want an event listener to be notified when switching from a network to another.

mfinkle, i don't care what is exposed to xul/chrome, but exposing it to the web has larger consequence.

Agreed. To hell with web content.

This bug is all about chrome. An Observer notifications would be perfect.

Would bug 531874 be related to this issue?
