listen to my MBP itunes library on my ipod in another room. Possible iPhone

Question #1: Without going out to buy anything fancy, is it possible to listen, on my wifes ipod touch in the baby room, to my MBP library over wifi? Ideally, Id like to somehow open music on the touch and see the exact same playlists as I would if I was on my MBP. I know you can share libraries over WIFI, but I dont think you can see these with an iOS device..is this correct?
Question #2: Similarly, is there anyway to view my MBP shared library playlists with our other computer, Macbook, for example? I know if you view shared libraries its just a jumble of songs not sorted into playlists.
Any help is greatly appreciated. Thanks!
