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 Vita’s settings application. Installing the plugin is also pretty straightforward if you only need to edit taiHEN’s 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 taiHEN’s 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
