I wouldn't say never, since emulating the Wii's online capabilities is "just" a matter of implementing the software interfaces (i.e. no need to emulate a whole network stack and stuff).. some of them can be redirected to plain berkeley sockets, some require network sniffing to reverse engineer their functionality.
Anyway, the devs aren't focussing on things like this, yet, so it'll take Dolphin a long time to acquire this functionality anyway...
