What Security topics would you like me to BlogCast about?

Eileen Brown has just posted an interesting article on her Blog which explains a new technique we're going to use to share snippits of content as she explains in the following extract of her post:

"Sometimes there just isn't time to view a whole Webcast, when all you want to do is learn something specific. Wouldn't it be great to have a demo and dialogue covering the exact component that you want to learn about?"

I'm really keen to understand what security topics you'd like to learn more about with regard to applying Microsoft Windows Security technologies - please provide feedback to this post.
