Decided to take my old-school GPL project FreePFM and try an experiment. Gonna write up some requirements, then implement it in PHP, Java (JSP + Servlets), J2EE (EJBs), .NET, Java Swing, and a standalone windows app. All apps will communicate with the same database. Should make an interesting project. I've wanted to learn some MS technologies for a while now, see what they're really like.
