The other major PF developers will also be in attendance and available to answer questiongs: Bob Beck (Edmonton) who did spamd, Mike Frantzen (USA) who did the state engine, Daniel Hartmeier (Switzerland) who started it all, Markus Friedl (Germany) who helped develop the grammar, and Henning Brauer (Germany) who integrated PF with ALTQ bandwidth shaping and pushed us to fix some early load problems.
