You've seen the PSP controlled by an Xbox 360 controller. You might have even seen the PSP controlled by a DualShock. Now see the PSP controlled by a Wii remote instead! It's as simple as connecting your homebrew enabled PSP to your PC wirelessly, then your Wii remote to the PC via Bluetooth, and finally having the PC translate the Wii remote information into PSP controls somehow. That is to say, it's not very simple and rather cumbersome. But at least it's possible, and that's the important part.
