Hacking via wifi
I would like to know, strictly for the sake of argument; if it's possible to hack a wii without needing a SD card.
Obviously Bootmii and priiloader are not options but what about HBC?
I would also point out that my internet connection would be supplied via a droid hot spot.
Hacking on the go!
That is an interesting question. I would have to say probably not. As far as I know the Wii is not capable of downloading files, nor could it unzip them anyway.
If I spelled something wrong, I'll just blame it on auto-correct :D
Once a system is modded, there are various apps that turns the Wii into an FTP server. You can then upload content to USB or SD over Wifi.
It's slow, but it works.
But the modding itself has to be done via SD card.
