Wii Warm Up: Voice chat

It seems like every time we bring up online multiplayer, someone else brings up voice chat -- or the lack thereof. It seemed worth further discussion, so we thought we'd ask: is the lack of voice chat in impending online Wii games a real problem for you? We rarely use it with other systems, so for us, it's not such an issue, but we know others often slap on the headset before descending into the field of online play. And of course, when playing online with friends, it is nice ... so perhaps it's a good match with friend codes after all.
