FreeEed.org: OpenSource eDiscovery Engine
Gartner projects that eDiscovery will be a $1.5 Billion market by 2013.
An open source project that compares to or exceeds the capabilities of other solutions would be a very interesting prospect.
Particularly if the software had an inherent capability to merge eDiscovery results from multiple sources, say multiple plaintiffs attorneys who had started on litigation separately, but now need to “merge” their discovery results.
