Awesme. Yes, multicast is the word I was looking for. If I added a Bluetooth sender would that connect trough the headphone jack? Then I could still connect one of the speaker units through the regular Bluetooth connection which would give me two available connections from my Blackberry Bold 9650. Do you think there would be any lag between the regular Bluetooth connection and the aux Bluetooth sender unit?
I was looking at the SuperTooth DISCO, Logitech Wireless Boombox , or the Soundfreaq SFQ-01 Sound Platform. They all have good reviews on Amazon. Do you know about any of these?
