Streaming ITunes To PS3

So i know for a long time you could not stream iTunes to PS3, but I've heard from a couple friends that have gotten it to work. Has anyone tried this that could tell me what steps to take to do this?

Edit - To clarify, I want to connect my iTunes from my iMac to my PS3 wirelessly or via bluetooth or whatever.

bump, in case people didn't see this.

I use PS3 Media Server on Windows 7, not sure if its supported on mac...

I simply share the itunes folder using it...

VUZE is whatg a lot of people use, however it does a poor job of transcoding video imo and crashed frequently for me. I believe there is a mac version.
