yeah there are several companies who make usb-to-ethernet adapters.
also a wireless g router is also pretty cheap
as for the gamecube:
try
Zelda: Windwaker
Battalion Wars
Super Smash Bros. Melee
Currently dreaming of: DKC4 or Sonic the Hedgehog 4 (classic 2D platformers) for WiiWare, Smash Bros. for DSi, New Super Mario World for DSi, a Wii remake or true sequel of Final Fantasy Tactics.
One down, hopefully more awesomeness to come.
