You're looking at the cleaned up final summary report to the funder of a research project. There isn't any CI. This wasn't a project to build a system. This was research to explore the possibility that operating system and application software can be radically simpler than it is today. Over a number of years they investigated many different systems which addressed aspects of the problem, wrote papers about them and yes made source codes and other artifacts available. It's (mostly) all here http://www.vpri.org/html/writings.php http://www.vpri.org/html/writings.php, http://tinlizzie.org http://tinlizzie.org, and http://tinlizzie.org/dbjr/ http://tinlizzie.org/dbjr/. So no, CI is not that hard. It's also not what they were paid to do.
