I’m working with folk all over the world, and I want to get a feel for their rhythms of online presence.

This would make a great skype API add-on. I want to be able to see a graph covering the last few hours or day or week showing a line graph for each person in my contact list’s online status, based on different colors. And then I’d like to see mood messages on rollovers or voice bubbles or something.

Perhaps over time it could be summarised into a display of ‘normal’ patterns. Like you get in the office. When people show up and leave. You get to know when people are going to be available.

Anybody feel like making this? I reckon it would be a hit API extension. I’m too busy on other stuff to do it myself. The only thing I ask is that you write it for OS X first :-)
