Subject: Re: BTsniff - Bleutooth sniffing under *nix

All,

During Renderman's talk @ defcon, he mentioned an email list where
development of an open firmware for sniffing bluetooth off the ether
was being developed.

I thought I had copied it down, but apparently I got it wrong because
there's nothing at the address I wrote down.

If there's concern this shouldn't be added to the interweb archives,
please send it to me off-list.

Regards,
N
