stop thinking in profiles. Profiles are applications and since we are in
the Linux world, yes, there are already some applications do deal with
certain profile definitions from the specification.

For PAN you can use pand and for object exchange there are lot of them,
but none of it is the default one. The IM chat would be tricky, because
there is no standard for it. However as Michal already posted, there is
a project for it.

Of course. It will show you the HCI packets when you establish a
connection from another terminal. If the device is idle you will see
nothing and if you run it a non-root you will see only a few packets.
