Another round of viral marketing: Secret Server
Secret Server is a web-based secret management system - it is the place to put all your passwords and other sensitive information and selectively share them with colleagues or team members. It is built in C#, ASP.NET with a SQL Server backend. It also has a web-based installer that developers might
find interesting.
It comes with one free user license so you can try it out now: http://thesecretserver.com
