Good stuff, i would from the 10 minutes i've spent since looking at this say (although i'm probably way off) they have a kernel exploit related/combination off the mii channel the sd card, and qr codes. I will say that i think gw will tread lightly on privileges and use kill code to try to prevent a simple reproduction without a need for a cart.
Other devs know of this exploit, and really if integrity and piracy is key to them then why let companies profit for it unless a) your scared of Nintendo (like graf with ps3) or b) on the take.
Like the ps3 scene earlier on, dev Deank does lots of freebie's in an anti-piracy method but is the biggest dev for cobra and on the take big time to release minimal teasers for cfw users with full functionality if you buy a (hardware) cobra usb dongle.
Maybe, just maybe, with all the time, effort, server requirenments?/server costs etc our own exploit homebrew dev might be a sheep in wolves clothing, setting him or her self up with community teasers on one side and a for profit situation without ramification from nintendo on the other. Money rules the world don't forget.
If thats the case and your not on the take, show some integrity now, anonymously shut them down with a scene release......
