ADC http://www.xemico.com/adc/index.html has it all. It's in-your-face on your desktop, interactive from the desktop, and uses notes and todo lists. It's highly configurable and shareable on a network. you can create note classes: birthday's, sport schedules, department, etc and assign them as private or public. No, it's not open source. This was the first downloadable software I ever purchased and it's been worth the price. Limited version is free to try. Runs on win98&up.
