Thanks,

I had a look and they definately would do the job. The price I
feel might be a bit high. For the same price one can buy a GSM
module with GPRS. Wasn't  bluetooth supposed to be a lot cheaper ?
Is US$80 for a bluetooth module about average ? For the application
I have in mind I need a price of below US$40 for low quantities.

Anton:

These ARE somewhat pricey, but they are Class 1 Bluetooth, which has 
enormous range: we routinely get 50 meters INDOORS with two Class 1 
devices.  In fact, I can remove the antenna and stick it in a steel 
filing cabinet and still get a good signal.

In any case, another alternative that we are starting to explore is 
www.blueradios.com which are also Class 1 devices and go down to $35 at 
100 pcs.  We just got the eval kit - if you ask again in a few weeks, i 
can let you know how things are going.

In our case, we require Class 1, and we've not seen any cheaper options.
