I just stumbled upon Klok and am addicted. I'm not letting this app go now.
With that said, some sort of XML export of data would be great to use in other projects. For example, the project currently being worked on could be used in a mini-app I would create that changes my chat client status to what I'm working on. I could also generate RSS feeds of projects and such to keep others updated, or even sync it somehow with Google Calendar.
Keep up the awesomeness!
