I am currently experimenting with an open source lab management program called OpenGoo. It allows users to set tasks and major milestones, to upload files, to set due dates, and to monitor progress on any number of individual projects. Aside from some minor hiccups with getting people in the lab to actually use it, I think it looks very useful. The success of software like this depends on the growth of a strong user community, so if you have a group of people in your lab and need a way to keep everyone organized and on target, I suggest you try it sometime.
