... Or any upcoming Wii accessories (who knows what will come from
these prolific brains ^^ ?); i guess a text input accessory will have
to come sooner or later. Yet, as you pointed out, here i'm interested
by the joystick + buttons

Exactly; but using the wiimote as gateway for it's accessories will:
* suck battery (wiimote & neo) -- bluetooth's fault
* require more pockets :p

I have no cparticular application in mind (apart the added input
methods -- 3D GPS navigation and games comes to mind ) ; in fact, what
i think is really great is that Nintendo uses I2C for accessories.
Which means, no need for OpenMoko to spread lots of accessories: just
go to your videogames retailer (huge existing distribution network),
pick up your favourite Nintendo accessory, and plug it in your I2C
expansion pack (adapter required).
