This homebrew app turns your 3DS into a remote desktop - shown running World of Warcraft
Modders are busy working on a Nintendo 3DS homebrew app which turns the system into a remote desktop.
A post on the gbatemp forum (thanks, Eurogamer) shows the app in action running World of Warcraft on a 3DS - although not perfectly.
At present, the app has a rather low frame-rate, but development is still in the early stages.
