A key reason for undertaking the Callisto release was to make it easier for individuals and organizations, like ISVs and enterprises, to adopt and integrate different Eclipse projects into their applications and projects. Therefore, we would like to highlight what people are doing with the projects that are included in Callisto.
Donald and I have started the Callisto Effect page, a list of quotes from different organizations. We are just getting started, so if you have plans to use the projects coming out in Callisto, send an e-mail to callisto.feedback@eclipse.org and we will post it.
