Web-based Network Login

[Slokunshialgo <slokun belligero org>]

Hello,

I've been looking into making an addition to NetworkManager to
automatically authenticate to networks with a web-based login process.
For example, you go to a cafe and they have a paid hotspot, you would
connect to the wifi, open a browser, and enter a username & password.
The idea is to automatically do then when connecting to the network.

The basic idea thus far is to use d-bus to connect NM to a Firefox
extension (starting it if need be) and pass a saved username and
password.  This extension would then use different things in Firefox to
login to the page, passing back success or failure.

Does anybody have any suggestions, or any problems with the proposed
idea?
