I have a friend who lives in the boonies and still only has dial-up (gasp!). She has a pre-Intel chip G5 Pro Desktop without an Airport Card. All she wants to do is stream music from iTunes to her audio system in a different room. Normally, if she wasn't on dial-up, and if she actually had an Airport Card, I know that this can be done easily. My question: can she install an Airport Card, buy an Airport Extreme base station to stream audio to her system without using an internet connection? Since she's on dial-up she's only connected when she needs to be, which is to check her email, so an always on dial-up wireless network seems...well, ridiculous.
