That is not possible since we have only one set of
modules for l2cap, rfcomm, bnep etc.
So even if I tell my app to use which adapter, only
one app will have exclusive access to the modules.
And the other app will be waiting for the first app to
free the modules.
A deadlock!

Mayank,
if you run "hciconfig" with two adapters connected, you see both hci0
and hci1. you also see their bdaddrs.
iirc, when you create a bt socket we usually set "any" as the source
(remember setting local_addr with bacpy(&local_addr, BDADDR_ANY) in
a2recv.c). you can use a specific adapter and that is what you have to
do when you have two adapters and you want to go out on a specific one.
when you connect to a service, obviously you can specify the bdaddress
to connect to.
most of the core bluez code will allow you to set the src address using
command-line arguments (a good example is -i <hciX|bdaddr> in hidd) but
we've been lazy in the btsco code about that.

this is simply wrong. No application will ever have exclusive access to
a kernel module. Or do you have to wait for your HTTP connection while
you are doing SMTP?
