Local tournaments possible?

[StrobeFlashLite]

I've been wondering for a few weeks now of how local Splatoon tournaments could be arranged.
Local tournaments could arranged by: having each player bring their Wii U and their copy of Splatoon (and have each player's Wii U and Gamepad marked to designate each player), and hooking up the Wii Us to a router via Wii U USB-to-Ethernet adapters to conserve bandwidth.
