Web browser object?
I think this project should try to include a web browser object as well. There are various java based web browsers out there (like the one integrated into NetBeans), and you could get a good start on the problem by absorbing one of those.
A web browser is a critical component of building useful user applications such as this. It allows nice formatting of help messages (for instance), and so much more. We don't want the users to always need to switch to a web browser to view every little piece of formatted data.
I think this would be a substantial help to the java community.
