DimDim is a free web-conferencing program from the open-source stable that takes on stalwarts like WebEx and LiveMeeting. DimDim is based out of United States, Canada, and India, and their demo looked great.
InfoWorld posted a review on DimDim soon after the product was launched at OSCON. Matt Asay said I’ve been tracking a cool startup since Linuxworld Boston, and was glad to see them formally launch at OSCON today. DimDim is the company, and they are to WebEx and web conferencing what SugarCRM is to Salesforce.com and Alfresco is to Sharepoint (and Documentum). An open source, value-rich competitor that should keep the proprietary competition up at night.
