I'm suprised it wouldn't be Virtual Console stuff...
Really, I imagine it probably would be. Much like Apple, I can't see Nintendo being too keen on allowing a complete emulator of any kind to be officially released for the Wii. But, I could easily see where Cloanto's license to distribute Amiga classic ROMs would come in very handy to bringing a few 'single title emulator' Amiga games to Wii as Virtual Console releases.
And as for UAE on a hacked Wii, it's been out for a while, and it's not bad. Though, ironically enough, I couldn't get it to use a Cloanto ROM, only a certain popular pirated one worked. :/
