Yes--it works for me.  However, the mac address referenced above 
required the address of my phone--not the adapter (which I had 
originally thought from the discussions and assumed).  I ended up trying 
a lot of different things--some of which may or may not have led to it 
eventually working (I'll post a follow-up once I get to what I think are 
the key steps).  I do know that the first "hoop" was to rebuild my 
custom kernel.org kernel (2.6.6) because the stock defaults don't enable 
the bluetooth modules and I didn't think to enable them on the prior 
kernel build.  Also, I'm virtually certain that I had to run "hciconfig 
hci0 up" to cause the adapter to be enabled (which makes sense if it 
follows the NIC analog).  Once the adapter was "up", I used hcitool to 
get raw info, scan and create connections.  I figured this needed to 
work reliably before I started playing w/ scripts that I didn't 
necessarily undertand.  FWIW: I'm using the Belkin class 1 adapter.
