I've started to build a generic connection type class, to simplify the network interfaces. Currently, a lot of code exists for each connection type, while it can often be done in a similar way. Furthermore, since there is no defined interface, interfaces often tend to duplicate the work. Connection type abstraction would allow to build interfaces faster and probably to simplify them.

This abstract connection_type class would be implemented for ethernet, isdn, mobile_data, pots, wireless, xdsl. The current draft allows to list devices for some basic types (ethernet, wireless, xdsl), and some GUI utilities (get human readable name and icon). It will be extented to list network and providers for a specific device.
