http://microblog.routed.net/2006/12/27/nintendo-wii-network-traffic-dumps/ I wanted to see what the Wii actually does with its wifi, so I put my laptop between it and the internet. Zip with all of the dumps but the one where I add wii point to my account is included in the above post. I am going to let it run overnight to see if I can capture background traffic with the unit in standby mode. If there is something specific that you want to look at let me know and I can try to get that traffic capture. Enjoy!
