This seems to be a question that needs to be clarified. Just to be brief, the answer is NO. As of today, It is not YET possible to scan via bluetooth into your computer for the following list of scanner manufacturers.
Why?
BLuetooth connection is usually a one way communication between two devices wherein one sends and the other one receives. Now for scanning this actually involve a more complex communication between two devices, therefore a more complex software/drivers and hardware for bluetooth devices. In my opinion, It is also impractical to pursue this, as we all new, better technologies like wi-fi, 3G, etc is already available.
