i'm not sure iff this is in the right forum, but here goes.

is there any way i can route audio to another speaker like Airtunes and AP Express does, but without ap express. let's say i have another computer that's hooked up to a better speaker, and it has itunes, and can see my PB's music via Rendevous. all this tiem i've been going back and forth to it to select the music i wanna play and do it manually. but is there any way i can make the PC itunes automatically play the music i select or command it to play from the PB??

i know it'd be easier with AP Express, but i don't have that yet. any ideas??
