Windows 7: This is so nerdy....

Wow, so I had this odd idea this week to find a little Windows Flag sticker so I can put it next to the word START on my car's ignition. I didn't stop there. I want to get a new stereo and my query is are there any car stereos out there in the realistic world that have programmable startup sounds? I want to use the vista beta startup sound (the Oracle of Delphi lady ). Or is there a way to wire that in such a way?

I mean come on, how cool is that?!
