How to stream from iTunes to the Sony PS3 (XMB)?

Does anyone know of any plugins, tricks or tips that allow me to stream directly from iTunes (on a Windows PC) to the XMB of the Sony PS3?

I know this is due to the incompatibility of the straming protocols (e.g. iTunes uses DAAP) but I have seen posts on the net getting this working, so I must be doing something wrong …

Other ways of doing it so far:

1. Using iTunes-PSP-Server, which streams via RSS feed and picking up via the Web Browser
