I have a wireless network set up using an airport express. Both my iMac and MacBook connect to it wirelessly. I want to use a second airport express and put it in my livingroom so I can connect my stereo speakers and use AirTunes. If I configure the second express to join the current network, will I be able to use internet and airtunes at the same time from the same computer? In other words, can I use the two airport express base stations in just one network with both internet sharing and airtunes? Thanks.
