Home Sharing Between Two iTunes Accounts

Hi,

My Dad has a vast amount of music on his itunes account and my old iPod used to be linked up to his account. But recently I got a iPhone 4 and I created my own iTunes account. I would like to be able to listen to the music on my Dad's account as well as the few songs I've purchased on mu account. Can I use home sharing (or something similar) so that I can listen to his music and my music on my iPhone?

Thanks in advance!
