digitalMASS - Mitch Kapor and "Chandler" vs. MS Outlook

This has been in the news a bit lately. Mitch Kapor, creator of Lotus 1-2-3, is attempting to build an open source Outlook competitor, currently named “Chandler”. He founded and runs the OSAF - Open Source Applications Foundation.

The technology page about Chandler is also interesting – combining Python, Jabber, Zope, RDF, and Mozilla.
