First of all, LOVE the plugin. I can't tell you how much time I searched for an "Author Box" that would work like I wanted in my particular theme.
I was able to make some mods to the plugin and added other social networks like flickr and tumblr. I updated the icon sets as well. Here is my sandbox site with the mods in place...

Has anyone tried to integrate Skype into it? I've played with a mod but cannot get it to work. What I envision is a skype icon that when clicked opens skype. Of course there needs to be a skype username field added in the profile in the admin.
