This is possible?

I dont believe so, but i am sure there is probably some phone application or bluetooth hack that would do this. I have an application on my phone called bluetooth hack which actually might do it, i am unsure as i don't use it.

Sorry friend, but the technology is not so advanced to send data to more than one person simultaneously. It can use only one bandwidth at a time, but my friends and I had tried once to transfer and receive at same time, and it worked. This means that when your device is receiving something from another device, then your device can also send some data to other device at the same time. But sending to more than one device at a time is not possible according to me. If there are any softwares available for this, then I am not aware of it.

i dont know about simultaneous sending but in my mobile o2 i have bluetooth which send to more devices in a queue manner that means one after another....

AFAIK,bluetooth is intended as a 1 application at a time channel,allowng access to your phone's bluetooth enabled devices such as headsets,printers,or file sharing. Leaving bluetooth permanently on when not paired with your devices is not recommended-it drains your battery faster,and phone hacking by bluetooth is apparently possible,so limiting the number of connections means the wanabe hacker has to be close enough to you physically to attempt anything!
