Sonos and iTunes

[satans worm]

HI
I have just moved into an apartment with Sonos fitted, the owner (im renting for 9 months) has left his music on the hard drive, and i dont want to delete/add any more to his hard drive, instead I would like to use either my iMac, iPhone or Apple TV on the Sonos system, is this possible? can i control it all from the Sonos remote? do i need to buy any new hardware to make this happen?

Thanks
