At ZendCon this year, Juliette Reinders-Folmer of phpwomen.org ran a session in the unconference entitled "Women in IT". In this session she invited the attendees (a fairly even mix of the genders) to discuss various aspects of women working in the male-dominated IT industry, and specifically in PHP. We were lucky enough (thanks Paul Reinheimer of php|architect!) to get the session recorded.
You can download the audio from the phpwomen.org website and check out the forum entry to continue the discussion. Their post also includes several talking points concerning women in the IT industry and how PHP Women can help.
