Project Management thoughts

Currently came across this proj mgmt tool called Scrum. It is nice but has its drawbacks. 

So let me pen (finger?) down some thoughts on what a simple project management tool can have:

•  LAMP based web app. 
• RBAC, who can add projects, who can add other users, modify schedules for what users etc.
• The point above entails user sessions.
• A primitive workflow - eg. user adds his tasks and timelines and an email is sent to the manager for approval before updating the db.
• Scratchpad for miscellanious ideas, thoughts, TBDs.
• Wiki integration.
• Atom feed server allowing folks to subscribe to important events/changes
• An integrated business calendaring system
• A known/unknown risks section

Other Funky stuff:

• A main page displaying newfeeds for related articles/projects in the industry from various news sources
  
• Reporting tools eg status graphs, can be per project as well as system wide, eg percent overshoot time for past projects
• Risk analysis tools (?)
• Integration with source code control and versioning systems (eg CVS) for software projects
• Keyword search/Advanced search
• Export to other tools such as Excel etc.
• Dependency tracking, which module depends on which etc.

Will add some more as I think further on this.
