Does anyone know of a good FOSS product that emulates the functionality of Lotus Teamroom? I am anal about my organization and much prefer a directory structure for it's ease of organization. I currently use a hacked verstion of Relay (http://www.ecosmear.com/relay) with a custom written XML parsing function to add context to directory and files for my Wiki-/teamroom- like functionality. However, is there a good alternative to this that a reader knows of?
