Wired Headset button - Change or Disable?

[NewYorkLaw]

When I ride my motorcycle, the button sometimes gets pressed accidentally and I call (and annoy) people. Is there a way (short of Krazy glue) to disable the button or reassign its function? It would be nice if that button could skip songs (mp3) or stations (fm radio) instead of dialing the last number called. I do use it to answer calls, though, but that's less important than stopping the unintended outgoing calls.
Suggestions?
