Hi, I have a set of speakers in my room that is on my desk, however I tend to use my MBP on my bed. I know that the airport express has the air tunes wireless streaming ability, but it looks like you need to have an ethernet cable connected in order for this to work even if you have an existing wireless network. I have an airport express, but I do not have an ethernet jack in my room. Is there any way to get the streaming capability without the ethernet cable? If not, is there another solution that would allow me to stream music over WiFi that I could plug my speakers into?
