A while back we mentioned that Red Hat was Clearspace's first customer. We've been excited about this for a number of reasons and a big one is that Red Hat planned to use Clearspace as the collaboration engine powering their Red Hat Exchange. We worked closely with their developers as they ultimately implemented a front-end that looks very different then Clearspace and shows exactly how customizable the application really is.  They did a fantastic job and brought a a lot of great ideas to their environment. Another reason we are excited is that Openfire, our open source Real Time Collaboration server, is one of the first applications listed in the exchange. We look forward to participating further on both fronts.
