Ok well my thoughts on Homebrew for the Wii.
1: It uses SD cards. (Omgz doesnt mean hacks!) Yes it could... you forget.. there is a .mov player and a photo viewer.. and if its coded right.. well.. its how the PSP hacks started.. all with a photo. ;)
2: The Gamecube used network adapter to connect to your PC which acted like a server with PSO. Wii connects too.. now if only it thought it was connecting to a server for the Wii Shop when in realty its connecting to your PC.. hrm hrm hrm..
3: Um... HRM! I didnt think of this... Think.. Gamecube Phantasy Star Online exploit.. well Wii PLAYS Gamecube yes?? Well... who said same exploit couldnt work??? I gotta try that...

Ok... darn.. PSO wont work for now.. it complains about not having a Gamecube network adapter connected.. darn.. didnt know it checks for it.. hrm.. but thats a idea to try if it would think its there..
