Port 25 has an interview with David Holder on Samba, IPv6 and Windows/Linux Interoperability. There is audio of the interview, plus links to slides from David's talk from SambaXP.

Here's a little teaser from the post:

One of the most informative sessions I attended was led by Dr. David Holder, an expert on IP networking and Windows/Linux interoperability. Specifically, he focuses on the IPv6 protocol, implementation, and interop, where he sees great opportunities for improved service levels in a range of applications and environments, but also sees a coming wave of interoperability problems between IPv6 implementations on various platforms.
