I'd actually put this into the WWAN factory, see just below:

                device = nm_device_factory_create_device (factory,
plink->name, plink, NULL, &ignore, &error);
                if (!device) {
                        if (!ignore) {

where &ignore is; the factory can indicate to the manager that it wants
certain devices ignored through that variable.  So you'd toss this into
src/devices/wwan/nm-wwan-factory.c::create_device() instead.

The one area of concern I have is whether or not these devices are reported as the proper type, otherwise they won't get passed to the wwan factory.

If this isn't a problem for us, then this seems like a reasonable approach... except for the fact that we've hard-coded these device matching expressions. Over time this won't scale.

Any thoughts about how this could be made runtime configurable? I'd love to get rid of one more source patch. ;)
