An idea for mobile phone application...

It just occurred to me that it would be good (well, at least for somebody) to have application that allows caller to define music/sound that will be played on a callee mobile phone. Basically, before you press Call button, you select a melody. This allows a lot of possibilities:

• Suppose, I'm angry and I'm calling my support administrator because something isn't working. In that case I can select some pretty loud yelling of the sentence like Answer the phone you idiot! The server isn't working again. And this can be repeated as many times as necessary.
• Or, if you are calling a wife because you've stayed with guys until late and you know she's currently mad. In that case you can select ringing tone something like: Hi Honey! I'm thinking on you and I'm calling you to appologize. with some appropriate background music.
• Or, if you are trying to get to some chick, you can use something like: Hey beauty, XYZ is calling you.
• Or, if you are calling your mother in law, you can use: Hey old bat! If you didn't drop dead answer the phone!

Well, you've got the point. The possibilities are endless. :)
