Case building and investigation tools

Anyone working with or seen something similar to

Analyst's Workbook

I'm looking for a tool that can be used to build up and visualize the people, evidence, events, etc that contributes to or are associated with a case under investigation as well as something that will help track progress in closing out the actions that arise for it...

Mind maps, spreadsheets, and harnessing some case management under bugzilla isn't really cutting it - just not integrated enough and is useless in cross correlating cases for trends, patterns, etc.

Thats really cool, something like this has so much potential. I'd want to write it. Sorry I don't know of alternatives.

What other features would an ideal tool like this have?

This sort of tool is the real world version of the stuff you'll see on CSI episodes with none of the glam or hocus-pocus.

I need tools to beef up internal investigations and am studying my BSC in computational intelligence to understand what's behind these types of tools and other behavioral pattern analysis techniques,and decision support systems.

The rest I can take offline, I was just throwing this out to get a feel for what else is in the market. My estimate is that you'll need about 2880 hours (160hrs/month x 3 developers for 6 months) to develop a non commerial version of what I'm looking for. If you're serious we can talk.

I think I''ll be too busy with studies for that kind of commitment. Are you going to be writing it anyway?
