Can you join multiple networks with or via the airport express? I have an apple tv as a stand alone network got my Apple tv, but while AP streams via ITunes, I'd also like to have Internet connectivity which requires my other network. Both the Airport Express & my router use septate WPA2 passwords. Is it somehow possible to stream to the apple tv via the eithernet port of the airport express, thus keeping the airport on the Mac kept free to connect to the home router for intrnet use.?
