Before you start playing, copy the memory card from one computer to all other computers that will be in the netplay session.
The write to SD card option is used to make SD cards read-only. Wii games don't use this for their save data, but there's a small number of games that use it for other things, like Super Smash Bros. Brawl.
I don't know when it will be possible to keep save data for Wii games on netplay.
