Many years ago, I discovered SnapperHead, a Mac OS X on-demand screen capture server. Itaka is meant to be a Linux port of SnapperHead.
Back then, showing my buddies on an instant messenger what I was doing was a cumbersome experience: Taking a screenshot, saving, and sending it. Long story short, Itaka for Linux was born. I am not going to explain the history of Itaka's development, I am only going to summarize it to this: Itaka took more than 4 years to have a stable initial release.
