Ok, so I want to stream music from iTunes to my analog stereo preamp, AND access files from an USB drive over the same wireless network. I've been lurking around the web for a solution for some time now. I've found ways to do dual wifi networks for different devices, but that doesn't solve my problem. In a perfect world, Airport Express and Airport Extreme would mate, have a baby, and call it the Airport Expreme. It would boast both a 3.5mm jack for music streaming and USB for an external HDD. Sadly this is not the case, so on to my question. As you can see from my photoshop hand-drawing skills below, my potential setup is (at least somewhat) simple in theory, but will it work in reality? If so, how would I set it up correctly? Easier ways to solve my dilemma is also appreciated! Thanks!
