Is there any way to use my Mac to control my Iphone?

I need to be able to use my Macbook as a remote control to play music from the ipod feature on the Iphone. Basically a reverse of the current Remote app.
I have never heard of an app on either end that support that, but may I offer a suggestion? Check out the Airport Express from Apple. It has a feature that allows you to stream music from iTunes to your sound system. I have one, and I love it! It's $99, and once you get it set up, all you have to do is click on a button in iTunes, and it sends your music over your wireless network.

Can the iphone control the itunes library on a pc? i mean as a remote control, i know it works on a mac ?

There is another app called Simplified Media it even amazing you can stream music from your desktop or laptop computer from anywhere.

Is there a way to control the iPod touch from a Mac?
I have my iPod touch hooked up to my stereo. I was wondering if there is an application or extension for iTunes that allows you to control what is being played on the iPod touch (or iPhone) remotely.
I know there is an application that allows you to control your Mac from the iPod touch but I'm not sure if there is one for the other way around.

Anyone who has an iphone, can you tell me if safari has parental controls for safari. Can you limit the sites your child goes to to a specific set like on a mac?
it's not there (I just checked). If you are really techy, you could set up a VPN or a proxy server... but any kid of a techy parent could circumvent it easily.
