Is it possible to purchase this product (BlueSoleil 8) one time, and installed on more than one computer. The computers have the same IP adress. If so, can it be installed on atleast 3 diffrent machines, or is it unlimited installation. Also, does it work well with Windows 7 Pro 64 bit. Lastly, is there a good bluetooth dongle usb that works great with Blue Soleil, has a good range (60ft and up), fast speed (3Mps and up), works with 7 Pro 64 bit, and can connect to atleast 7 devices and still have good quality.
