I don't know too much about this, but its a new channel in development.
Here's what was listed:
This is a demo of the Wii Homebrew Channel beta, powered by devkitPPC / libOGC. These apps are being loaded off an SD card. The channel also has built-in support for loading ELFs/DOLs via USBGecko and TCP/IP (shown at the end, when Linux is loaded).
