The Wii port needs a virtual keyboard like other ports have them too. (WinCE, PSP, NDS, ...)
I suggest to revive the vkeyb thingy so that all ports can benefit from this.
If noone is willing to maintain this, I suggest joining forces between the ports that need a virtual keyboard. It should be less work for all if they work together on a common thing than if every one implements his own virtual keyboard. :-)
