The PSVita Scene is rocking, heres a release that lets you control your PSVita with a wiimote:

ViiMote is a homebrew plugin that lets you use your PSVita with a WiiMote. Setting it up is pretty simple as you can use the Vitaís settings application. Installing the plugin is also pretty straightforward if you only need to edit taiHENís config file (config.txt). This is all possible because Nintendo uses Bluetooth for the Wiimote instead of something proprietary.

Pairing instructions:
◾Enable viimote.skprx in taiHENís config.txt
◾Go to Settings > Devices > Bluetooth devices
◾Press the 1 and 2 button simultaneously on the Wiimote for 2 seconds
◾The Wiimote should connect automatically
