You might want to check out the Women Who Tech Teleconference, which is taking place via phone/web on May 23rd. For a nominal fee, you can attend several panel discussions revolving around programming/development and entrepreneurship.
The topic list isn't geared toward "Women Who SysAdmin", but I might find myself there just to check out the discussion on Digital Rights and Online Privacy. One of the panelist is Kaliya Hamlin, the founder of She’s Geeky, which is a favorite conference of mine for women.
So check it out and see if it's up your alley!
