I would like to to see full Bluetooth protocol support in Ethereal and
try to help you whereever possible.

The program hcidump supports the native hcidump file format and also the
BTSnoop file format. I might need to send you a patch for it at some
point.

Post a pre-patch to this mailing list and I am going to have a look at
it.

These are not really in use at all at the moment. I need to write a test
program to show them to you.

Let me see if I can get you some nice BNEP transmission. Once you get
BNEP on top of L2CAP you can hook it into TCP/IP then.
