Is there anyway of getting a ps3 to mimmick an airport express, and being able to play a song in itunes, on my computer, and hear it come out of my ps3 and therefore my sound system. if this is possible, i could change the song from my ipod touch, and that would be awesome. i don't really want to by an airport express, so please dont suggest that. also, i know that there is software available to stream files (such as null rivers's medialink), but i would very much like to select the song on itunes, rather than on the ps3. thanks alot!
