It seems that Nintendo isn't quite as draconian as we thought about the Wii Download Ticket code accompanying new purchases of the WiiSpeak microphone. Previous statements
suggested that there was absolutely no way to obtain a code without purchasing new hardware -- even if you have
bought new hardware and require a replacement code.
The statement from Nintendo of Europe reads "Any consumer who may have misplaced their Wii Download Ticket number for the Wii Speak Channel
or require a new number following a Wii exchange may contact their local Nintendo Customer Services department, where they can request a replacement Wii Download Ticket number."
There's no word of secondhand purchases or any other circumstances, but it seems likely that if Nintendo is at all willing to offer replacement codes, the friendly customer service representatives won't be too stingy with Download Ticket codes. Just don't buy a used WiiSpeak expecting
to get the free code.
