There are many more that normally haven't taken a deep marketing track (and that remains a challenge).

For example check out colama - http://www.colama.net - using VMs for college education; http://www.emee.co.in/ (note - this is my employer's product) - gamification of enterprise workflows, and http://www.kpoint.com/ - which allows you to record videos and embed them in the website (and often used in many conferences, for internal company presentation).
