Awesome list! Thanks so much for sharing! Here are some of the Podcasts hosted by women in my playlist:

ANOMALY and ANOMALY SUPPLEMENTAL- Two geek girl shows on one feed. They're fun, hilarious at times and very smart. It features topics for just about everyone (Dr. Who, Star Trek, Star Wars, cosplay, costuming, convention reports... all from a female perspective) : http://www.anomalypodcast.com

WOMEN TALK SCI-FI- another great geek girl show. They always have awesome celebrity interviews and, like Anomaly, they attend lots of conventions and report on them. Both of these shows have been around for about seven or eight years and are high quality. http://womentalkscifi.com/
