The current version of the specification does not answer the whole problem; Indeed, a way to make sure that a request goes through a specific interface (does not have to change the network) would be ideal.

Dan> Network Interface API is required for switching networks and checking signal strength. But Network Information API is also useful to enable the use cases like video adaptive streaming (e.g. SD on 3G, SD or HD on WiFi), and warning user to turn on WiFi before a big download or video streaming to save the purchased data quota.
