A new toy , and when I eventually got it sorted , it works fine. A simple set up , and I assume that Apple / iTunes have something similar but this'll do me. I have Winamp running on my main PC , but you need to download Winamp Remote and have this running on your home PC.
Then you set up an account account and in the web settings on your ASUS Eee, selecting Realplayer (which I generally detest as a product) as the preferred streaming method , this seems to use the browsers (Firefox) inbuilt player. So now I can have my music anywhere as long as my PC is running!!
